Answer:
Sarah is right.
4/5 = 8/10
Step-by-step explanation:
A proportion is when you set up two ratios (they look like fractions) equal to each other.
4/5 ?=? 8/10
CROSSMULTIPLY.
4×10 ?=? 5×8
40 = 40
They are equal to each other. You could kind of tell by inspection. Like if you times the 4/5 × 2/2 you get 8/10.
Another way to check on a calculator is to divide. 4÷5 equals 0.8 ALSO, 8÷10 same, also equals 0.8
