Question

Lucy is a dress maker. She sews \dfrac47

Answer 1

Answer:

$\frac{16}{21}$ dresses

Step-by-step explanation:

We are given that

Lucy sews dress in 3/4 hours=$\frac{4}{7}$ of dress

Lucy sews at constant rate.

We have to find the number of dresses sewed by Lucy in hour.

To find number of dress sewed by Lucy in 1 hour we will use unitary method.

By using unitary method

Lucy sews in 3/4 hours=$\frac{4}{7}$ dress

Lucy sews in 1 hour=$\frac{\frac{4}{7}}{\frac{3}{4}}$

Lucy sews in 1 hour=$\frac{4}{7}\times \frac{4}{3}$

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

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