Question 1out of 10
Calculate 19.958 + 16.892
Align the decimal points and corresponding place values. Add trailing zeros if needed. Add from the right, carrying when necessary, and keep the decimal point aligned. For example, 2.35 + 1.4 = 3.75.
Question 2out of 10
Calculate 18.79 + 13.23 × 0.8
Perform decimal multiplication or division before addition. For multiplication, multiply as whole numbers and then place the decimal point using the total number of decimal places in both factors. For division, multiply both numbers by the same power of 10 to make the divisor a whole number.
Question 3out of 10
Select the correct match 329⁄100
Convert a fraction to a decimal by dividing its numerator by its denominator. A denominator of 10, 100 or 1000 requires one, two or three decimal places respectively. For example, 7/100 = 0.07.
Question 4out of 10
Calculate: 2.64 + 2.74.
Align the decimal points and corresponding place values. Add trailing zeros if needed. Add from the right, carrying when necessary, and keep the decimal point aligned. For example, 2.35 + 1.4 = 3.75.
Question 5out of 10
Express 94% as a decimal.
Percent means hundredths. Divide the percentage number by 100, moving the decimal point two places left. For example, 7% = 0.07 and 125% = 1.25.
Question 6out of 10
Find 0.7 of the number 17
To find the stated part of a number, multiply the number by the fraction or decimal multiplier given in the question.
Result = a · b.
If a is given as a percentage, first convert it to a fraction: a% = a / 100.
Question 7out of 10
Calculate: 4.88 × 10.
Multiplication by 10 moves the decimal point one place right; multiplication by 100 moves it two places. Add zeros if needed. For example, 2.35 × 10 = 23.5 and 2.35 × 100 = 235.
Question 8out of 10
Calculate: 9.88 × 100.
Multiplication by 10 moves the decimal point one place right; multiplication by 100 moves it two places. Add zeros if needed. For example, 2.35 × 10 = 23.5 and 2.35 × 100 = 235.
Question 9out of 10
Calculate: 11.51 − 5.13.
Align decimal points and add trailing zeros if needed. Subtract from the right, regrouping one unit of a higher place into ten units of the next place when necessary. Keep the decimal point aligned. For example, 4.2 − 1.35 = 2.85.
Question 10out of 10
Calculate 19.81 − 11.11 × 0.7
Perform decimal multiplication or division before addition. For multiplication, multiply as whole numbers and then place the decimal point using the total number of decimal places in both factors. For division, multiply both numbers by the same power of 10 to make the divisor a whole number.

Operations with decimals
For decimal addition and subtraction, align decimal points. For multiplication, calculate without decimal points first and then place the point using the total number of decimal places in both factors.
Division
To divide by a decimal, make the divisor a whole number by moving the decimal point by the same number of places in both numbers. Check the result with an estimate.
