The ratio of boys to girls at school today 4:7. If there are 350 boys at school today, how many girls are there? Round down

If we know the ration is 4:7, we know that both 4 an 7 need to be multiplied by the same exact number to equal 350. That leads us to set up the following equation:

4x + 7x = 350

We combine like terms to get:

11x = 350

We divide by 11 on both sides to get:

x= 31.82

7x represents the number of girl so :

7 * 31.82 = 222.72

Because the question says to round down, the answer is 222
