3. Mr. Miller has 5 girls and 6 boys in his class. Write a part-to-whole ratio to represent his class

A part to whole ratio is 5:11

Step-by-step explanation:

There are 5 girls which is a part and 11 which is 5 plus 6 and that is a whole

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)
