(15+3) / (15 - 3) solve within the parenthesis first 18/12 Then simplify the fraction 3/2 or 1 1/2 * * * * * The above answer has assumed parentheses when none were specified. 15 plus 3 over 15 minus 3 is 15 + 3 / 15 - 3 division comes first so: 15 + 0.2 - 3 then addition: 15.2 - 3 then subtraction: 12.2
11/15 - 3/15 = 8/15
2/3
2/5 minus 1/15 is 1/3
it is 4 over 15
2/3 minus 12/15 is -2/15

11/15 - 3/15 = 8/15
2 minus 5 is -3, sooo your answer should be negative 3 over 7.
3/5 − 3/15 = 2/5
2/3
2/5 minus 1/15 is 1/3
10/15 - 3/15 = 7/15
3/5 − 4/15 = 1/3
it is 4 over 15
n=-4/3
8/15 - 3/15 = 5/15 or 1/3
