Whenfinding a fraction of a number, such as 1/4 of 12, children in Year 3 are taught that they need to divide the number 12 by the denominator (bottom number) of the fraction. So 1/4 of 12 is 12 ÷ 4, which equals 3.
Here, they need to understand that since the left hand side equals 16, the right hand side has to equal the same amount, since 20 - 4 = 16, the number in the gap should be 4. They may be given a number sentence like the one above, but where there is not one answer to put in...
Multiplication and Division:In mathematics, to determine two numbers that multiply to give another number, x, we simply divide x by any other number, a, and a times the result will give x. That is, if x÷ a = b, then a× b = x. We can use this fact to determine numbers that ...
