Year 3: More missing numbers

I have had a number of requests for more pages similar to the ‘Find the Missing Numbers’ published in May, so here is another.

The questions are all similar:

e.g. Find a pair of numbers with a sum of 7 and a product of 12.

Pairs of numbers with a sum of 7 are:

1 and 6

2 and 5

3 and 4

(it is not necessary to go on to 4 and 3 etc) as these have already been found.

Pairs of numbers with a product of 12 are:

1 and 12

2 and 6

3 and 4

Look for the same pair and the answer is 3 and 4.
