to find 1,188 divided by 12. I think about 1,200 divided by 12 that's groups 100of 12. 1,188 has fewer group of 12

Sergio [31]

To find 1,188 divided by 12. I think about 1,200 divided by 12 that's groups 100 of 12. 1,188 has fewer group of 12

Answer: If we divide 1200 by 12, we will get 100 12's in 1200.

But our question is 1188 divided by 12.

So the difference between 1200 and 1188 is 12. Therefore there will be 99 12's in 1188.

Therefore, 1188 divided by 12 is 99.

Also I have shown in the image attached how 1188 divided by 12 is 99.
