Which ratios form a proportion

Mathematics
1 answer:
Lelu [443]2 years ago
3 0

Answer:

C

Step-by-step explanation:

To form a proportion, you need two equal ratios.

Divide the numerator by the denominator of all fractions.

Any two fractions that are equal are a proportion.

A.

4/9 = 0.4444...

9/4 = 2.25

Fractions are not equal. Not a proportion.

B.

4/10 = 0.4

10/25 = 0.4

Fractions are equal. Proportion

C.

4/11 = 0.363636...

6/13 = 0.46153846...

Fractions are not equal. Not a proportion.

D.

I can't read the fractions, but do the same I did above.

Divide each numerator by the denominator and compare the decimals. If they are equal its a proportion. If theya re not equal, it is not a proportion.
