##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”##
