QUESTION

What are equivalent ratios 7 to 10?

##14/20" and " 21/30##

A ratio can be expressed in 2 ways. Using a 'colon' or as a fraction.

That is 7 : 10 (reads 7 to 10) or ##7/10##

To find equivalent ratios it is probably best to use fraction form.

##7/10" is in "color(blue)"simplest form"##

This means that no other number, apart from 1, will divide into 7 and 10.

In this case we can choose any number to multiply the numerator and denominator, to create equivalent ratios.

##color(red)"Choosing 2"##

##rArr(7xx2)/(10xx2)=14/20larr" equivalent ratio"##

##color(red)"Choosing 3"##

##rArr(7xx3)/(10xx3)=21/30larr"equivalent ratio"##
