Question

simplify by using suitable property 3\5×(-7\8)+1/6(-1/2)×3/5​

Answer 1

Answer:

1) - 86/105

2) 47/120

Step-by-step explanation:

1)   2/3 * - 4/5 + 2/3 * - 3/7

2/3( - 4/5 + - 3/7)      (distributive property)

2/3( - 4/5 - 3/7)

2/3(- 28/35 - 15/35)   (taking LCM as 35)

2/3( - 43/35)

2/3 * - 43/35

- 86/105

2)   3/5 * 7/8 + 1/6 - 1/2 * 3/5

3/5( 7/8 - 1/2) + 1/6     (distributive property)

3/5( 7/8 - 4/8) + 1/6

(3/5 * 3/8) + 1/6

9/40 + 1/6

54/240 + 40/240    (taking LCM as 240)

94/240

47/120
