Question 281943
convert them to the same denominator
2/3 +3/4
multiply 3*4=12
the first fraction is 2/3
12/3=4
so multiply both numeration and denominator by 4 that is by 4/4 which is really 1 in disguise
4/4*2/3=8/12
next fraction
12/4=3
multiply 3/4*3/3=9/12
so now we have 8/12+9/12
add 8+9=17

17/12
now reduce the improper fraction to a mixed number
17/12= 1 5/12 done
so we did
2/3+3/4
3*4=12
2/3*4/4+3/4*3/3
8/12+9/12
17/12
1 5/12
