Leo is correct because he earns £7 each week as there are 7 days

in a week. £7 x 11 = £77, so he will have £2 remaining after buying

his new smartwatch.

In 11 weeks I will have enough money

to buy a new smartwatch.

Reasoning 2

Joanna is thinking about the 7 times table.

She says,

Is she correct? Explain your answer.

Joanna is correct because if 7 x 9 = 63, then the answer needs to be

multiplied by 10 as 90 is 10 times more than 9. Therefore, 7 x 90 = 630

is correct.

If I know that 7 x 9 = 63, then I can

work out that 7 x 90 = 630.
