Sebastian made the following model to find the product 17 x 24 is his model correct explain

No, it is not correct.

Step-by-step explanation:

Here, the given problem,

17 × 24

∵ 17 = 10 + 7

And, 24 = 20 + 4

Thus, 17 × 24 = (10 + 7)(20 + 4)

= 10 × 20 + 10 × 4 + 7 × 20 + 7 × 4

= 200 + 40 + 140 + 28

= 408

By comparing the above steps and Sebastian's model,

It is clear that he did incorrectly multiply 7 by 20,

i.e. he must write 140 instead of 40 while adding.

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer
