What are two ratios equivalent to 3:11

Answers

A ratio given as p : q can be written as a fraction(p)/(q)

If we multiply the numerator and the denominator of the fraction (p)/(q) with 2 or 3, fraction remains unchanged.

(p)/(q) =(2p)/(2q)= (3p)/(3q)

Following the same rule, ratio given as 3 : 11 can be written as,

(3)/(11)= (3* 2)/(11* 2)= (3* 3)/(11* 3)

(3)/(11)= (6)/(22)= (9)/(33)

Therefore. equivalent ratios to 3:11 will be 6:22 and 9:33.

There are a few ways to do this

When doing a ratio, its a comparison of numbers which often is was multiplied and then compared

So since you can't find a common factor above one to make it smaller, you have to multiply instead.

You can multiply each side by 3 and it would be 9:33 and it would be equivalent to
 3:11 if you divide each side by 3

Other examples:

Multiplying each side by 5⇒ 15: 55

Multiplying each side by 10⇒30:110 

Express 5/7 as a decimal.
