Multiply these fractions (lowest terms)
a) 2 x 3/4 b) 3 x 3/5 c) 4 x 1/3 d) 6 x 2/5
e) 1/2 x 1/4 f) 4/5 x 2/3 g) 5/6 x 3/4
h ) 1/10 x 2/3 i) 2 1/5 x 1/2 j) 1 1/2 x 2 1/3
k) 3/4 x 2 3/4 l) 6 2/3 x 2 1/8

For Q's a to d
a) 2 x 3/4 = 6/4 = 1 2/4 = 1 1/2
b, c and d follow the same pattern

For Q's e to h we use fraction multiplication:
f) 4/5 x 2/3 = 8/15

For Q's i to l we have to change the mixed numbers to top heavy fractions and then multiply:
j) 1 1/2  is equal 3/2 and 1 1/3 is equal to 4/3
Therefore 1 1/2 x 1 1/3 = 3/2 x 4/3 = 12/6 = 2

I hope that this gives you enough information to go on
