a) -11-(-5)
= -11+5 = -6
b)15 x (-3) = -45
c) (-3) x (-7) x (-5)
= 21 x (-5) = -105
d) Change 1 1/2 to improper which is 3/2
3/2 / 2 = 3/4
e) Change both fractions to improper
22/5 x 38/5 = 836/25 or 33 11/25
f)Get the LCD of all fractions which is 70
175/70 + 30/70 - 28/70 =177/70 or 2 37/70
= -11+5 = -6

Sorry e) is 22/5 x 38/7 = 836/35 or 23 31/25
