Please help me out !

Answer 1

a)
`(-9)/(-10)` b)
`(-3)/(5)` ,
`-(3)/(5)`

Explanation:

a) Since the fraction you are dealing with,
`(9)/(10)` , is positive, we will need to find a fraction that has either two negative numbers or two positive numbers. The first option,
`-(9)/(10)` , the entire fraction is negative, which does not match the given fraction. The second option,
`(-9)/(10)` , only one number is negative, and that does not match either. The third option,
`(9)/(-10)` , is the same as the second option, only one negative number. However the last option,
`(-9)/(-10)` , has both a negative number in the numerator and denominator which both cancel out to
`(9)/(10)`, making the fraction positive.

b) The fraction we are dealing with here,
`(-3)/(5)` , is negative, so we need to find a fraction that has only one negative number. The first option,
`(3)/(5)` , has no negative numbers, making it positive, which does not match. The second option,
`(3)/(-5)` , has one negative number, which matches our fraction. The third fraction,
`(-3)/(-5)` has two negative numbers making the fraction
`(3)/(5)`, positive, which does not match. Then the last option,
`-(3)/(5)` the whole fraction is negative which matches our fraction.
