a 1/7 + (-5/16)
b (-1/7) + (-5/16)
c (-1/7) - (-5/16)
d - (1/7 - 5/16)

Answer 1

It have to be A or D

Explanation:

Answer 2

Answer: B.
`(-(1)/(7) ) + (-(5)/(16) )`

Explanation:

To solve this, you have to find the answer to what is being compared.

`-(1)/(7)-(5)/(16)=-(51)/(112)`

a.
`(1)/(7)+\left(-(5)/(16)\right)=-(19)/(112)`

b.
`\left(-(1)/(7)\right)+\left(-(5)/(16)\right)=-(51)/(112)`

c.
`\left(-(1)/(7)\right)-\left(-(5)/(16)\right)=(19)/(112)`

d.
`-\left((1)/(7)-(5)/(16)\right)=(19)/(112)`

Therefore, b is the answer
