Answer 1

Answer:

The answer of this sum is 11/45.

Answer 2

Given :

• -2/3 × 5/6 -2/3 × 4/7​

To find :

• using appropriate property find the value of -2/3 × 5/6 -2/3 × 4/7​

Solution :

⇒ Here, we have to find the Value of -2/3 × 5/6 -2/3 × 4/7​ using Appropriate property. So, let's use Distributive Property.

→ Distributive Property for Subtraction =  (a x b) - (a x c)

Here,

• a = -2/3
• b = 5/6
• c = 4/7

⇒ Let's solve!!

= (a × b) + (a × c)

= (-2/3 × 5/6) - (-2/3 × 4/7)

= (-2 × 5/3 × 6) - (-2 × 4/3 × 7)

= (-10/9) - (-8/21) [LCM of 9 and 21 = 63]

= (-10 × 7/9 × 7) - (-8 × 3/21 × 3)

= (-70/63) - (-24/63)

= (-70 - (-24)/63

= -46/63

Therefore, the value of -2/3 × 5/6 -2/3 × 4/7​ is -43/63.
