Question

Sandra wants to use the fact 4 × 8 = 32 to help her find the product of 7 and 8. Drag the tiles to explain how she could do this. Tiles may be used once or not at all. 3 × 8 added to

Answer 1

3 × 8 added to(4*8) gives 7*8= 56

Step-by-step explanation:

Suppose we have 32 tiles and we deduct 8 tiles from it then we get (32-8=24) meaning 3 times 8 is 24 as we have subtracted 1 times 8 from 4 times 8.

as 4* 8= 32

then 3*8= 24

Now we want to find 7 * 8 so we add the two products 3times 8 and 4 times 8

(4*8)+ (3*8)

32+24= 56

This can be done as follows.

(4*8)+ (3*8)

Taking 8 common gives

8(4+3)

8*7= 56
