## anonymous 4 years ago 4(3/5)*7(1/4)=(667/20) how i keep getting 6440/20

1. ash2326

tabby it's $4 \frac {3}{5}* 7 \frac{1}{4}$ so it's equal to $(4+ \frac {3}{5})*(7+\frac{1}{4})$ now we get $( \frac{23}{5})*(\frac{29}{4})$ so we get $\frac{667}{20}$

Got it??

how did you get 23 and 29

4. ash2326

$$4\frac{3}{5}$$ and $$7\frac{1}{4}$$ are mixed fractions, Do you know mixed fractions?

5. ash2326

$4\frac{3}{5}=4 + \frac{3}{5}= \frac{4*5}{5}+\frac{3}{5}=\frac{20}{5}+\frac{3}{5}=\frac{23}{5}$ Similarly $7 \frac{1}{4}= \frac{29}{4}$
