Question

Write the ratio 5:30:20 in lowest terms.

explain the answer please

Answer 1

1: 6: 4

Explanation:

In order to turn a ratio into the lowest terms, we must find the Greatest Common Factor (GCF) of the terms:

Factors of each number:

5: 1, 5

20: 1, 2, 4, 5, 10, 20

30: 1, 2, 3, 5, 6, 10, 15, 30

Notice any common factors between all numbers: 1, 5

Based on the common factors, we know that 5 is the Greatest Common Factor (GCF).

Now, divide each term by the GCF:

5:30:20 =

5/5 : 30/5 : 20/5 = 1: 6: 4
