Workmen used 9/10 of a pallet of pavers to build 9 steps leading up to the mansion. Each step they built was the same size. How many pallets did they use for each step?Write your answer as a fraction or as a whole or mixed number. pallets
Solution
The workmen used 9/10 of a pallet of pavers for 9 steps. To find out how many pallets they used for each step, you need to divide the total amount of pallets used (9/10) by the total number of steps (9).
Step 1: Write down the problem. 9/10 ÷ 9
Step 2: Convert the whole number into a fraction. 9/10 ÷ 9/1
Step 3: To divide fractions, you multiply by the reciprocal of the divisor. The reciprocal of a number is 1 divided by that number. So, the reciprocal of 9/1 is 1/9. 9/10 x 1/9
Step 4: Multiply the numerators (top numbers) of the fractions to get the new numerator. Multiply the denominators (bottom numbers) of the fractions to get the new denominator. (9 x 1) / (10 x 9) = 9/90
Step 5: Simplify the fraction. Both 9 and 90 can be divided by 9. 9 ÷ 9 / 90 ÷ 9 = 1/10
So, the workmen used 1/10 of a pallet for each step.
