1. The ratio of boys to girls in the sixth grade is 2 : 3. a. If there are 24 boys, how many girls are there?
b. If there are 80 students, how many are girls?
c. If there are 75 students, how many more girls are there than
boys?

a. 36 girls

b. 48 girls

c. 15 more girls than boys

Step-by-step explanation:

a. if the ratio for the question is 2:3 with a refernce ratio of 24:X, with cross multiplication we find out the x=36

b. now we must separate 80 into the 2:3 ratio making 32:48 with 48 girls

c. the same thing will be done with 75, making its 2:3 ratio 30:45, to find the difference of the two numbers you must subtract, this shows that the difference is 15 more girls.

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
