At Daria's school, 3/8 of the students are left handed. If there are 320 students, HOW MANY OF THEM ARE LEFT-HANDED?

120

Step-by-step explanation:

(Sorry, I originally put this in the question category, oops!)

To find the answer to this problem, the easiest way would be to convert 320 into a fraction (320/1) so then it's:

3/8 x 320/1 because you want to find the equivalent fraction of 3/8.

So it's 3 x 320/8 x 1 (or 3 x 320/8)

This is equivalent to (32 x 3) x 10/8

So the answer is (96 x 10)/8 = 960/8 or 960 divided by 8, again, an easy way to do this is (96/8) x 10, and after doing that math you get 96/8 = 12 and 12 x 10 is 120.

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

it would be 6xy and -16xy.
