Answer 1

\[1 \frac{ 3 }{ 4 }\]

Because the two halves add up to be 1 and there's still the 3/4 so you add that to the end which makes it: \[1 \frac{ 3 }{ 4 }\]

Answer 2

I'd suggest identifying and then using the lowest common denominator of these three fractions first.

What is the LCD?

How many of the fractions already have the LCD?

How do you "fix" any that don't, so that in the end all of the fractions have the same denominator (LCD)?
