Question

over three successive Collins build 1/3, 1/5 and 1/4 of the brickwork of his new garage. What fraction must he complete on the fourth and final day​

Answer 1

1 - 1/3 - 1/4 - 1/5

Explanation:

Let's take it one step at a time.

Day 1 he completes 1/3 of the garage, so you subtract 1/3 from 1 which means he left 2/3

Day 2 he completed 1/4 more, so you again subtract, this time though 2/3 - 1/4, or in other words 1 - 1/3 - 1/4

So you do this one more time. 1 - 1/3 - 1/4 - 1/5

Can you handle this or do you need help with fraction subtraction.
