Answer: To find the ratio equivalent of 49:21 in simplest form, we need to divide both numbers by their greatest common factor (GCF).
First, let's find the GCF of 49 and 21:
The factors of 49 are 1, 7, and 49.
The factors of 21 are 1, 3, 7, and 21.
The common factor(s) of 49 and 21 is 7.
Now, we can divide both numbers by 7 to simplify the ratio:
49 ÷ 7 = 7
21 ÷ 7 = 3
Therefore, the ratio equivalent of 49:21 in simplest form is 7:3.
