#4 and 4/35# or #144/35# depending on what you want to leave your answer as...

(improper fraction or mixed fraction)

Explanation:

assuming you mean mixed fractions or #2# and #4/7# and #1# and #3/5#

Change these into an improper fraction (numerator bigger than denominator):

#2 and 4/7#=#14/7+4/7=18/7#

#1 and 3/5#=#5/5+3/5=8/5#

Then multiply the results from this:

#18/7 xx 8/5#

Multiplying numerators:

#18 xx 8=144#

Multiplying numerators:

#5 xx 7=35#

Then put the first result over the second, again giving a improper fraction:

#144/35#

This is the fully simplified improper fraction. You can leave it at this, or you could turn it back into a mixed fraction:

#35 xx 4=140#

#therefore# the mixed number is #4#

Minus the original number by the number given:

#144-140=4# This is the numerator

Also, the denominator stays the same. Giving:

#4 and 4/35# or as I said you could leave it as an improper fraction as #144/35#
