It depends on what the problem looks like. Do you mean A or B below?
A: (2 1/6) * (1 3/5) / (4/11) + 1/3
B: (2 1/6) * (1 3/5) / (4/11 + 1/3)
A: (2 1/6) * (1 3/5) / (4/11) + 1/3
make any mixed fractions into improper fractions
(13/6) * (8/5) / (4/11) + 1/3
the / can turn into a * if you flip the 4/11 like this:
(13/6) * (8/5) * (11/4) + 1/3
when you have fractions times'd together, you can combine them like this:
(13*8*11) / (6*5*4) + 1/3
1144 / 120 + 1/3
reduce. divide the top and bottom of 1144 / 120 by 8
143/15 + 1/3
143/15 and 1/3 have different bottoms (denominators), so we can't add them together.
3 goes into 15, so 15 is the "least common multiple" of 3 and 15
multiply the top and bottom of 1/3 by 5
143/15 + 5/15
now the bottoms are the same, so we can add the tops (numerators) together like this:
(143+5) / 15
148 / 15
turn it back into a mixed fraction
9 13/15
