Lucy is a dress maker. She sews 4/7 of a dress in 3/4 hour. Lucy sees at a constant rate. At this rate, how many dresses does lu

IgorLugansk [536]

Answer:

Lucy sews $\frac{16}{21}$ dresses in 1 hour.

Step-by-step explanation:

Given:

Lucy sews $\frac{4}{7}$ of a dress in $\frac{3}{4}$ hour.

She sews at constant rate.

We need to find the number of dresses she makes in 1 hour.

In $\frac{3}{4}$ hour = $\frac{4}{7}$ dress

So in 1 hour = Number of dresses in 1 hour

By using Unitary method we get;

Number of dresses in 1 hour= $\frac{\frac{4}{7}}{\frac{3}{4}} = \frac{4}{7}\times \frac{4}{3}= \frac{16}{21}$

Hence Lucy sews $\frac{16}{21}$ dresses in 1 hour.
