Answer 1

Please explain in steps.

Answer 2

Write the mix fractions as improper fractions like so:
\[Q \frac{R}{D} =\frac{D \cdot Q+R}{D}\]

Answer 3

\[\frac{5 \cdot 5+1}{5} \cdot \frac{4 \cdot 4+1}{4}=\frac{25+1}{5} \cdot \frac{16+1}{4}=\frac{26}{5} \cdot \frac{17}{4}\]

Answer 4

3 4/5 x 2 2/8 =

Answer 5

\[\frac{26}{5} \cdot \frac{17}{4}=\frac{26}{4} \cdot \frac{17}{5}=\frac{13}{2} \cdot \frac{17}{5}=\frac{ 221}{10}\]

Answer 6

5 1/5= 5.2
4 1/4= 4.25
5.2 X 4.25= 22.1

Answer 7

I will be happy to check your answer. Look what I did above and try to do that here or you can do what michu is doing which is writing both as decimals and then multiplying. (his second reply is right :))

Answer 8

Just change both of the fraction to improper fraction and the divide it by the denominator and lastly you would multiply it.
