In a school there are 75 girls in the tennis squad. the ratio of the numbers of boys in the tennis squad to the number of girls in the tennis squad is 4: 3. work out the number of boys in the tennis squad

100 boys

Step-by-step explanation:

boys: girls

     4:3

We want to get the girls to 75

3 *what = 75

Divide each side by 3

3*what/3 = 75/3

what is 25

We need to multiply by 25 on both sides.  The ratio will stay the same

boys: girls

25* 4:3*25

100 : 75

There are 100 boys

step-by-step explanation:

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
