Definitely false. A liquid ounce is much smaller than one cup of the same liquid, let alone two cups of the liquid.
Answer:
7/4 + 9/-5 =
Since the denominator of the second fraction is negative the sign will change from negative to positive
We will get
7/4 - 9/5
First find the LCM
LCM of 4 and 5 is 20
7/4 - 9/5 = 5(7) - 4(9)/ 20
Simplify
We get
35 - 36/20
= -1/20
Hope this helps
The answer is the first one: 1 1/5 because 120/100 = 1.2
