Simplify using the identity −2 /7 x 1/5 + 1/3 - 4/5 x - 2/7​

Mathematics

ElenaW [278]3 years ago

Answer:

1/3 + 6/35

Step-by-step explanation:

We are given;

−2/7 × 1/5 + 1/3 - 4/5 × -2/7

Using the rule of bodmas, we will group them and solve with multiplication being the first operation.

1/3 - (4/5 × -2/7) + (−2/7 × 1/5)

Factorization of first and second bracket gives;

1/3 + 2/7(4/5) + 2/7(-1/5)

Factorizing again gives;

1/3 + 2/7(4/5 - 1/5)

>> 1/3 + 2/7(3/5)

>> 1/3 + 6/35
