Question

4) Using properties calculate the
following
a) (-4/5)(3/7) + (4/5)x(3/7)
b) (12)< (5/6) + (1/3) × (1/4)​

Answer 1

Step-by-step explanation:

a) (-4/5)(3/7) + (4/5)×(3/7)

= -4/5×3/7 + 4/5×3/7

= -12/35 + 12/35

= 0

b) (12)<(5/6) + (1/3)×(1/4)

= 12/1×5/6 + 1/3×1/4

= 60/6 + 1/12

= 10 + 1/12

= 10/1 + 1/12

= 120/12 + 1/12

= 121/12

Answer 2

Step-by-step explanation:

(-4/5)(3/7) + (4/5)x(3/7)

b) (12)< (5/6) + (1/3) × (1/4)
