solve please .............please ........

Answer 1

a)-11-(-5) = -11+5 = -6

b)15*-3 = -45

c)(-3)*(-7)*(-5) = -105

d)1(1/2)÷2 = 3/2÷2 = 3/4

e)3(7/5)*5(3/7) = (22/5)*(38/7) = 836/35 = 23(31/35)

f)(5/2)+(3/7)-(2/5) = (175+30-28)/70 = 177/70 = 2(37/70)

Answer 2

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
