Which ratios form a proportion

Mathematics
1 answer:
Lelu [443]1 year 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.

A bouncing ball reaches a height of 54 inches at its first peak, 36 inches at its second peak, and 24 inches at its third peak.
steposvetlana [31]
54, 36, 24 are the 1st 3 element of a geometric progression with 2/3 as a common ratio: PROOF:
the 1st term is 54, (a₁= 54) the 2nd term a₂ = 24, then
(a₂ = a₁.r) or 36 = 54.r → r= 36/54 = 2/3. Same logique for the 3rd term. 
So 2/3 is common ratio. We know that :U(n) = a.(r)ⁿ⁻¹. Then if a =54 and r = x (given by the problem), then f(x) = 54.xⁿ⁻¹
n, being the rank of any element of this geometric progression
