Hi Musfirah, when you see the word 'equal to', it means that the numerator are the same. This is why we have to multiply 3 to 4/7 to give us the answer of 12/21 (oranges), then multiply 4 to 3/5 to give us the answer of 12/20 (apples)

Then we take 21 units (total no. of oranges) + 20 units (total no. of apples) = 41 units (total no. of oranges and apples in the fruit store)

41 units -> 2050
1 unit -> 2050/41 = 50

21 units - 20 units = 1 unit

Ans: Therefore there are 50 oranges more than apples in the fruit stall
