soooo
in order to do this both fractions has to have the same denominator
so you find the CMD (common denominator)
which is 4
so you'd only change 5/2
5/2 * 2/2 to make it 10/4
now both fractions have the same denominator
you do keep change flip
you keep 10/4
change division to multiplication
and flip 3/4 TO 4/3
which would equal
10/4 * 4/3= 40/12
40/12
and you divide it with long division
you get 3 as ur quotient
divisor as 12
and remainder as 4
= 3 4/12
nd u simplify which u divide 4/12 by 4 and get 1/3
so the answer would be 3 1/3
and in order to check you can use an online fraction calculator
