Answer 1

\(\Large \color{MidnightBlue}{\Rightarrow x + {5 \over 4} = {15 \over 4} }\)
Converting from mixed fractions to improper fractions.


\(\Large \color{MidnightBlue}{\Rightarrow x = {15 \over 4} - {5 \over 4} }\)

\(\Large \color{MidnightBlue}{\Rightarrow x = {15 - 5 \over 4} }\)

\(\Large \color{MidnightBlue}{\Rightarrow x = {10 \over 4} }\)

\(\Large \color{MidnightBlue}{\Rightarrow x = 2{2 \over 4} = 2{1 \over 2} }\)

Answer 2

2 1/2 + 1 1/4 = 3 3/4 which equals to 3.75
