Question

It takes Avery 3/4 hour to paint 1/5 of a painting. At this rate, how long will it take her to complete the painting?

Answer 1

Answer:

It will take Avery 3 hours and 45 minutes to complete the painting.

Step-by-step explanation:

Time that it takes Avery to paint 1/5 of a painting = 3/4 hour

How long will it take her to complete the painting?

Time that it takes Avery to paint 1/5 of a painting = 3/4 * 60

Time that it takes Avery to paint 1/5 of a painting = 45 minutes

Time that it takes Avery to complete the painting = 45 minutes * 5

Time that it takes Avery to complete the painting = 225 minutes

Time that it takes Avery to complete the painting = 225/60

Time that it takes Avery to complete the painting = 3 hours and 45 minutes

It will take Avery 3 hours and 45 minutes to complete the painting.

Answer 2

Answer:

It will take 3.45 hours to complete a painting

Explanation:

Given

It takes every ¾ hour to paint 1/5 of a painting

Let us consider complete painting to be 1

According to the principle of unitary method,

1/5 of painting = ¾ hour

Complete painting =  $\frac{3}{4} \div \frac{1}{5}$

=  (3/4)*5 = 15/4 hours

15/4 hours = 3.75

Hence, it will take 3.45 hours to complete a painting
