Question

How do I get the ans??

Answer 1

11

406 - 278 = 128, then we know that there aren't gonna be an exact set so we think, well the closest one we can get to 128 is by multiplying 11 by 12, giving 132. So we know he must buy a minimum of 11 sets!

Hope this Helps!

Answer 2

11 sets of forks

Explanation:

First subtract 406-278 to find total amount of forks needed which is 128 forks.

Then divide 128 by 12 to see how many sets of forks you need.

You get 10.67 but because you can't buy two thirds of a set, you have to round up to 11 sets of forks.

Hope this helps :)
