GRADE 8 Mathematics – Decimals Quiz

0.75 is equivalent to 3/4 as it represents three-quarters of a whole.

0.03 is the smallest decimal number among the choices as it represents the smallest value.

4.8 divided by 2 equals 2.4. The result is obtained by performing division on decimal numbers.

0.6 is the same as 6/10 when expressed as a fraction.

The product of 0.5 and 2.5 is 1.25. Multiplying decimal numbers requires keeping track of decimal places.

0.98 is the largest decimal number among the choices as it represents the greatest value.

1.2 written as a percentage is 120% because the decimal is moved two places to the right to convert to a percentage.

Three-fourths is represented as 0.75 in decimal form because it is equivalent to 75 hundredths.

Adding 1.25 and 2.5 results in 3.75. The sum of decimal numbers involves adding the numbers while considering the decimal point.

One-half is equivalent to 0.5 in decimal form because it represents half of a whole.

0.4 simplifies to 2/5 as a fraction in its simplest form by dividing both numerator and denominator by 2.

Subtracting 0.6 from 1.2 gives 0.6. The difference between decimal numbers involves subtraction while considering the decimal point.

0.9 is equivalent to 9/10 as it represents nine-tenths of a whole.

0.25 squared is equal to 0.0625. To square a decimal number, simply square the digits and then adjust the decimal point.

0.8 divided by 0.2 equals 4. When dividing decimals, you may need to move the decimal point to obtain a whole number result.

Five-eighths is correctly represented as 0.625 in decimal form because it is equivalent to 62.5 hundredths.

Multiplying 0.6 by 10 gives 6. To multiply a decimal by a whole number, you can simply ignore the decimal point initially.

Four-fifths is equivalent to 0.8 in decimal form because it represents 80 hundredths.

The difference between 0.7 and 0.35 is 0.35. Subtracting decimal numbers involves aligning the decimal points and performing subtraction.

0.12 is equivalent to 12% when expressed as a percentage because the decimal is moved two places to the right to convert to a percentage.

0.16 divided by 0.8 equals 0.2. Dividing decimals may require moving the decimal point to obtain a whole number result.

Three-tenths is equivalent to 0.3 in decimal form because it represents 30 hundredths.

Adding 1.75 and 0.25 gives 2. When adding decimal numbers, align the decimals and perform the addition.

To convert a decimal to a fraction, write the decimal as the numerator and the place value as the denominator. Therefore, 9.3 is equivalent to 93/10.

When comparing decimals, the smaller the number, the greater the value. Therefore, 0.26 is the smallest number among the choices given.

To add decimals, line up the decimal points and then add as usual. The result of 4.7 + 2.15 is 6.85.

To convert a decimal to a percentage, move the decimal point two places to the right and add a percent sign. Therefore, 0.78 is equivalent to 78%.

To multiply decimals, ignore the decimal points and multiply the numbers as if they were whole numbers. Count the total number of decimal places in the factors and place the decimal point in the product accordingly. The result of 3.25 x 4.7 is 15.28.

To simplify the fraction, divide both the numerator and the denominator by their greatest common factor (2 in this case). Therefore, 1.2 is equivalent to 6/5.

When dividing decimals, move the decimal point in the divisor to make it a whole number, then move the decimal point the same number of places in the dividend. The result of 0.0035 divided by 0.07 is 0.05.

A terminating decimal is a decimal number that ends or terminates. Therefore, 0.625 is a terminating decimal, while 0.3333 repeats infinitely.

To convert a decimal to a percentage, move the decimal point two places to the right. Therefore, 0.75 x 100 = 75.

To find how much is left, subtract the amount eaten from the initial amount. In this case, if you eat 0.35 of 0.6, then 0.25 of the pizza is left.

To multiply decimals, ignore the decimal points and multiply as if they were whole numbers. Count the total decimal places in the factors and place the decimal point in the product accordingly. The result of 5.25 x 0.8 is 4.2.

An irrational number is a number that cannot be written as a simple fraction. Therefore, 1.414 is an example of an irrational number as it is the square root of 2.

To find how much is left, subtract the amount consumed from the initial amount. In this case, if you drink 1.75 liters from 2.5 liters, then you have 0.75 liters of water left.

To convert a decimal to a percentage, move the decimal point two places to the right. Therefore, 0.45 is equivalent to 45%.

To convert a decimal to a whole number, move the decimal point three places to the right. Therefore, 0.009 x 1000 equals 9.

To convert a whole number into a decimal, place the decimal point after the number. Therefore, 6.25 is equivalent to 6.25.

When comparing decimals, the greater the digit in the first decimal place, the larger the number. Therefore, 0.789 is the largest among the choices given.

To find how much fabric is left, subtract the amount cut from the initial amount. If you cut 0.95 meters from 1.6 meters, then you have 0.65 meters of fabric left.
