-10

-20 -(-5) = -15 ie -(-5) = +5 therefore -20 +5 =15 (two double minuses = a positive)

5, as 20x0.75=15, so 20-15=5

9 - 20 / 4 + 16 = 9 - 5 + 16 = 20

16/20 - 5/20 = 11/20

Negative 15 plus positive 20 equals 20 minus 15, which equals 5.

9 - 20 / 4 + 16 = 9 - 5 + 16 = 20

16/20 - 5/20 = 11/20

15/16 - 3/8 = 21/16 - 6/16 = 15/16

It is: 5/12 minus 3/20 = 4/15

3/5 - 3/4 = 12/20 - 15/20 = (12 - 15)/20 = -3/20

Converting to twentieths, we get 8 over 20 minus 15 over 20, resulting in minus 7 over 20.
