Question

Amy knits 1/10 of a scarf in 4/5 of an hour. What fraction of scarf can Amy knit in 1 hour

Answer 1

Answer:

Amy can knit $\frac{1}{8}$ of a scarf in 1 hour.

Step-by-step explanation:

This question can be solved by proportions, using a rule of three.

We have that:

1/10 of a scarf - 4/5 of an hour

x of a scarf - 1 hours.

Applying cross multiplication:

$\frac{4x}{5} = \frac{1}{10}$

$x = \frac{5}{10*4} = \frac{5}{40} = \frac{1}{8}$

Amy can knit $\frac{1}{8}$ of a scarf in 1 hour.
