9/6 + 4/6 = 13/6 = 2 and 1/6
2 over4, 1 over2
4/3 since 1 and 1/3 = 3/3 + 1/3 = (3+1)/3 = 4/3
A whole contains 3 thirds. 3 wholes contain 9 thirds (1/3+1/3+1/3)=1 (1/3+1/3+1/3)=1 (1/3+1/3+1/3)=1
1 - 1/3 = 3/3 - 1/3 = 2/3
3/4 > 1/2
3/5 - 1/2 = 1/10

1/2 = 50%
9/6 + 4/6 = 13/6 = 2 and 1/6
7 over2
7 1/2 - 4 1/6:= 7-4 + (1/2 - 1/6)= 3 + [(3 - 1)/6]= 3 + 2/6= 3 + 1/3= 3 1/3
The LCD for working with those fractions is 8 (or 1/8)
10 - 41/2 = 51/2

% rate:= (3/2) x 100%= 1.5 x 100%= 150%
1/2 ÷ 7/8 = 4/7
