Question

Please help!!! I am so confused!

Answer 1

Q#1 (look at the picture)
Answer: C

Q#2
a reciprocal number of
`(a)/(b)` is equal
`(b)/(a)`

therefore

a reciprocal of
`(2)/(7)` is equal
`(7)/(2)=\boxed{3(1)/(2)}\to\boxed{D}`

Answer 2

the first one is c because if you put it at negative 1/8 then it is 0-1/8 or 1/8 away from zero

second one is
the reciprocal is the number that when multiiplied by the number you are trying to find the reciprocal of, you get +1 so the number you have is 2/7 so
2/7 times x=+1
multiply both sdies by 7/2 to clear fraction
x=+7/2
the reciprocal is +7/2 or +3 and 1/2 which is D
