Divide 60 by 2/3 to find the class total.
= 60 ÷ 2/3
to divide fractions, multiply by reciprocal of 2/3
= 60 * 3/2
multiply numerators
= (60 * 3)/2
= 180/2
= 90 total students
CHECK
= 90 total * 2/3
= (90*2)/3
= 180/3
= 60 which is 2/3 of class
ANSWER: There are 90 total students
Hope this helps! :)
