Write the ratio in the lowest terms. 20 ft to 12 ft

jenyasd209 [6]

Answer:

5 ft : 3 ft

Step-by-step explanation:

Ratios are always fractions so we can turn this to a fraction; $\frac{20}{12}$

Then to reduce to it's lowest terms divide by a number that can divide both of them. Lets divide by 2 since it can divide the two numbers

$\frac{10}{6}$

We can still divide by 2 since it can divide both numbers = $\frac{5}{3}$

Since no number can divide both of them at the same time the answer is $\frac{5}{3}$ OR 5 ft : 3 ft
