Question

A. 7/4 +1/2
b.5/3+2/5

c.3/2+4/6

d. 7/5+1




a)-12/5-(3/11)

b) -27/32-2/7

Answer 1

A. 7/4 +1/2 
       (14 + 4)/8 = 9/4

b.5/3+2/5 
        (25+6)/ 15 = 31/15

c.3/2+4/6 
         (18+8)/ 12 = 13/6

d. 7/5+1
               (7+5)/ 5  =   12/5





a)-12/5-(3/11)
 
(-12 x -11) - (5x3) /  5 x 11

121-15/55       = 106/55


b) -27/32-2/7
    (-27 x -7) - (32 x 2) / 32x7
          189 - 64 /  224  =   125/224
