Question

Allison can sew three scarves in 75 minutes. How many scarves can she sew in four hours?

Answer 1

9.6 or 9 whole scarves

Explanation:

You have to change the 4 hours into 240 minutes.

You can set it up as a proportion.

`(3)/(75)` and
`(x)/(240)`

Then you need to set it up as:

75 x = 240 · 3

Then you get:

75 x = 720

Now you set it up as:

x = 720 ÷ 75

When you divide you get 9.6.

So, X = 9.6.

Allison can sew 9 whole scarves in four hours. The answer could also be 9.6 scarves. Not sure which one you need.

Answer 2

2.4

Explanation:

75/3=25.

So she can do 1 scarf in 25mins

60/25=2.4

she can do 2.4 scarfs in one hour
