Answer 2

Answer: Using the property the value of 2/7 × -2/3 + 3/7 × -2/3 is -10/21.

Step-by-step explanation:

Given expression is, 2/7 × -2/3 + 3/7 × -2/3

1. Write it as, ( 2/7 × -2/3 ) + ( 3/7 × -2/3 )
2. Analyse distributive property and take -2/3 as common from both terms, i.e a(b+c) = a×b +a×c.
3. -2/3 [ 2/7 + 3/7 ]
4. -2/3 [ ( 2 + 3 ) / 7 ]
5. -2/3 × 5/7
6. - ( 2 × 5 ) / ( 3 × 7 )
7. - 10/21.

∴ the solution is -10/21.
