Question

-3/5(3/7+(-5/6))
Find

Answer 1

Answer:

17/30

Step-by-step explanation:

The arrangement of the given rational number is as per the rule of distributive law over addition

. = (-3/5) × {(3/7) + (-5/6)}

The LCM of the denominators 7 and 6 is 42

(3/7) = [(3×6)/ (7×6)] = (18/42)

and (-5/6) = [(-5×7)/ (6×7)]

= (-35/42) = -3/5 [(18 – 35)/42] = -3/5 [-17/42] = (-3/5) × (-17/42) = 51/210 … [divide both denominator and numerator by 3] = 17/30

Answer 2

Answer:

17/70

Step-by-step explanation:

=> -3/5 x (3/7 - 5/6)

=> -3/5 x (18/42 - 35/42) {LCM}

=> -3/5 x (-17/42)

=> 51/210

=> 17/70 (Simplified){Ans.}
