<PRE><B>Question 784258</B>
7/5 * ?/? = 18 3/4 my twelve year old needs help solving this
Convert 18 3/4 to an improper fraction
18*4 + 3 = 75, so we have
{{{7/5}}} * ____ = {{{75/4}}}
____ = {{{75/4}}} divided by {{{7/5}}}
When you divide fractions, invert the divisor and multiply
____ = {{{75/4}}} * {{{5/7}}}
Multiply the numerators and the denominators resulting in
{{{375/28}}}
To convert back to a mixed number use long division 28|375 you should get
13 11/28
