The answer is 2. I'm guessing this is a homework question - therefore - I'll leave you to work out how you get to the answer !
It is 13/72 minus 3/8 = -7/36
13/20 minus 3/5 is 1/20
10 - -3 = 13
4/3 minus (-3/8) is 1 17/24
negative 2 over 6
negative 4 over 3 .
-15633
2 minus 5 is -3, sooo your answer should be negative 3 over 7.
-3/11 − -4/11 = 1/11
19/20 minus 3/10 = 13/20
-1/5 minus -2/7 is 3/35
-h/3 -4 = 13 -h -12 = 39 -h = 39+12 -h = 51 h = -51
