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?

Sagot :

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

[tex]\frac{2}{5}+\frac{3}{10}=\frac{6+1}{10}=\frac{7}{10}[/tex]

Comparing to Nicole's work

[tex]\begin{gathered} \frac{4}{5}=0.8 \\ \frac{7}{10}=0.7 \\ \frac{4}{5}-\frac{7}{10}=\frac{1}{10} \end{gathered}[/tex]

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