A pattern has 15 blue triangles to every 20 yellow triangles. What is the ratio of yellow triangles to all triangles?

Explanation:

There are 20 yellow triangles and 15+20 = 35 triangles total.

The ratio of yellow to total is 20:35. The order is important.

We divide both parts by the GCF 5 to get the reduced ratio 4:7

There are 35 total triangles, so the ratio of yellow to all triangles is 20 / 35

or 20 to 35 or 4 to 7

Step-by-step explanation:

4 & 3

step-by-step explanation:

factor of 108=2×2×3×3×3=2×2×3^3=the number is 4 because 2 only occurs 2 times and 2×2=4 and factor of 2187=3^3×3^3×3=the number is 3 because 3 onlyvoccur 1 time.

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
