What are equivalent ratios 7 to 10?

Answer 1

Riley Anderson

#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"#
