How do you divide #1 2/ 6\div 1/ 3#?
1 Answer
Explanation:
The key to division of fractions is to reciprocate the divisor (what comes after the division sign) and change the division sign to multiplication.
In this case, we have a mixed fraction so we change it to an improper fraction first.
How do we do that?
Simple!
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.
So for
#(6*1)+2#
#6+2#
#8#
So our numerator is
Back to our question;
#1(2)/6-:1/3#
#4/3-:1/3#
Reciprocate
#4/3xx3/1#
Multiply the numerators and the denominators.
#12/3#
Reduce the fraction if possible
#=(4xxcancel(3))/cancel3#
