Question

Evaluate B-( - 1/8) + c where b =2 and c=- 7/4

Answer 1

Answer: 3/8

Explanation:

Given:

`B-(-(1)/(8) )+c`

replace variables with their given values: b = 2 and C = 7/4

`2-(-(1)/(8))+(-7)/(4)`

to make subtracting and addition easier, make each number has the same common denominator.

`(16)/(8) -(-(1)/(8))+((-14)/(8))`

Finally, solve equation.

***remember that subtracting a negative is the same as just adding and adding by a negative is the same as simply subtracting.

`(16)/(8) -(-(1)/(8))+((-14)/(8))=(16)/(8) +(1)/(8)-(14)/(8)`

= 3/8

Answer 2

3/8

Explanation:

2 - (-1/8) + (-7/4)

= 17/8 - 7/4

= 17/8 + -7/4

= 3/8
