Question

Heather puts together 2/5 of a puzzle on Saturday and 3/10 on Sunday. Nicole has the same puzzle, and she puts together 4/5 of her puzzle. How much more of the puzzle does Nicole put togelther than Heather?

Answer 1

So Nicole put together 1/10 of that puzzle more than Heather did.

1) Gathering the data

Heather on Saturday

2/5

Heather on Sunday

3/10

Nicole

4/5

2) Let's add those ratios up for Heather's work

`(2)/(5)+(3)/(10)=(6+1)/(10)=(7)/(10)`

Comparing to Nicole's work

`\begin{gathered} (4)/(5)=0.8 \\ (7)/(10)=0.7 \\ (4)/(5)-(7)/(10)=(1)/(10) \end{gathered}`

3) So Nicole put together 1/10 more than Heather did.
