Multiply these fractions (Lowest Terms)
forsale [732]
For Q's a to d
a) 2 x 3/4 = 6/4 = 1 2/4 = 1 1/2
<span>b</span>, c and d follow the same pattern

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

For Q's <span>i</span> 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
