The ratio of boys to girls in our class is 4 to 5. If
there are 8 girls, then how many total students are
in the class?

Respuesta :

Answer:

6.4/6

Step-by-step explanation:

Since

4 : 5 = X : 8

Then we know

4/5 = X/8

Multiplying both sides by 8 cancels on the right

8 × (4/5) = (X/8) × 8

8 × (4/5) = X

Then solving for X

X = 8 × (4/5)

X = 6.4

Therefore

4 : 5 = 6.4 : 8
