Question

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

Answer 1

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
\[ \frac{667}{20}\]

Answer 2

Got it??

Answer 3

how did you get 23 and 29

Answer 4

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

Answer 5

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