The women's department of a store stocks 4 types of black socks for every 5 types of white socks. The men's department stocks 6 types of black socks for every 7 types of white socks. If each department has the same number of black socks, which department stocks more types of white socks?

Answers

Answer:

The women's department of a store stocks have more types of white socks.

Step-by-step explanation:

Given:

The women's department of a store stocks 4 types of black socks for every 5 types of white socks.

Ratio of black socks to white socks = 4 : 5

The men's department stocks 6 types of black socks for every 7 types of white socks.

Ratio of black socks to white socks = 6 : 7

Each department has the same number of black socks.

Question asked:

Which department stocks more types of white socks?

Solution:

Let each department has 100 black socks.

For women's department

4 : 5 : : 100 : white socks

$(4)/(5) =(100)/(White\ socks) \n\n By \ cross \ multiplication\n \n 4* White\ socks=100*5\n 4White\ socks=500\nBy\ \ dividing\ both \ sides\ by\ 4\nWhite\ socks=125$

For men's department

6 : 7 : : 100 : white socks

$(6)/(7) =(100)/(White\ socks) \n\n By \ cross\ multiplication\n \n 6White\ socks=100*7\n6White\ socks=700\nWhite\ socks=About\ 117$

We found that out of 100 black socks the women's department of a store stocks have 125 white socks while the men's department stocks have about 117 white socks then by default understood that the women's department of a store stocks have more types of white socks.

Answer:

The women have more
