The ratio of girls to boys at Hopkins Middle School is 4 to 5. There are 360 girls at the school. How many total students are enrolled?

Question 3 options:

450

810

648

288

810 students.

Step-by-step explanation:

The 4 part of the ratio represents 360 girls.

Divide 360 by 4 for the value of one part of the ratio.

360 ÷ 4 = 90 ← value of 1 part of the ratio, thus

5 parts = 5 × 90 = 450 ← number of boys

Total number of students = 360 + 450 = 810

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
