How do you evaluate #2\frac { 7} { 10} \times 4\frac { 2} { 3}#?
1 Answer
Explanation:
To multiply that, rewrite the mixed fractions as improper fractions.
Take the denominator of the mixed fraction, multiply it by the whole number and add the numerator. Whatever value you get becomes the numerator of the improper fraction over the denominator of the mixed fraction.
For
#(10*2)+7#
#20+7#
#27#
So our numerator is
For
#(3*4)+2#
#12+2#
#14#
So our numerator is
Now to the question;
#27/10xx14/3#
Multiply the numerators and the denominators or cancel out numbers which are factors or multiples of each other.
Using
#cancel27^color(red)9/10xx14/cancel3^color(red)1#
Using
#9/cancel10^color(red)5xxcancel14^color(red)7/1#
Now multiply the numerators and the denominators.
