Question

choose the fractional notation for the ratio problem below. simplify the fractional notation if possible.
mikayla drew 20 triangles and 25 circles on a piece of paper. what is the ratio of circles to triangles?
20 ÷ 5 = 4
25 ÷ 5 = 5
25 ÷ 5 = 5
20 ÷ 5 = 4
45 ÷ 5 = 9
25 ÷ 5 = 5

Explanation:

Step1: Write the ratio

The ratio of circles to triangles is \(25:20\). In fractional notation, it is \(\frac{25}{20}\).

Step2: Simplify the fraction

Divide both the numerator and denominator by their greatest common divisor. The GCD of 25 and 20 is 5.

$$ \frac{25\div5}{20\div5}=\frac{5}{4} $$

Answer:

\(\frac{25}{20}\div\frac{5}{5}=\frac{5}{4}\)
