Given:
1/2 X 3/7- 5/7 X 1/2+2
To Find:
To simplify the given expression.
Solution:
We have to use the BODMAS rule to simplify the given expression. BODMAS is a rule to solve an expression. BODMAS stands for, 'Brackets, Order, Division, Multiplication, Addition, Subtraction.
1/2 X 3/7- 5/7 X 1/2+2
We have to operate Multiply first,
⇒ 3/14 - 5/14 +2
Now, we have to operate in addition
⇒ 3/14 - (5+28) /14
⇒ 3/14 - 33/14
At last, we have to do Subtraction
⇒ (3-33)/14
⇒ -30/14
⇒ -15/7
∴ 1/2 X 3/7- 5/7 X 1/2+2 = -15/7
