what are proportion?
Proportions are a way of showing that something equals this. Here are some examples to solve and just examples:-
Examples:-
1. \(\frac{1}{3}= \frac{2}{6}\)
♥1 × 2 = 2
♥3 × 2 = 6
2. \(\frac{10}{20} = \frac{15}{x}\)
To solve for x we will do the following:-
Cross multiply:-
15 × 20 = 300
Divide:-
300 ÷ 10 = x
300 ÷ 10 = 30
x = 30
So our proportion will now look like:-
\(\frac{10}{20}= \frac{15}{30}\)

A proportion in math is when two ratios are equivalent, that means they are equal to each other.
Example of a proportion:
4/5 = 8/10
Since they are equal, they are proportional.
