Answer 2

What is \(2\large\frac 34\) in fraction?
What is \(1\large\frac 45\) in fraction?

Answer 3

no, negative one is a whole number & i dont know

Answer 4

\(\large 2\frac 34 = \frac{4*2 + 3}{4} = \frac{8+3}{4} = \frac{11}{4} \)

\(\large 1\frac 45 = \frac{5*1+4}{5} = \frac{5+4}{5} = \frac{9}{5} \)

\(\large 2\frac 34 - 1\frac 45 = \frac{11}{4} - \frac{9}{5} = ?\)

Answer 5

\(\large \frac{11}{4} - \frac{9}{5} = \frac{11*5}{4*5} - \frac{9*4}{5*4} =
\frac{55}{20} - \frac{36}{20} =\frac {55-36}{20} = \frac {19}{20}
