Since the the second fraction is negative and you are subtracting, remove the negative sign and switch the operation to addition.
The equivalent equation is
115+196=?
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(11/5, 19/6) = 30
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(115×66)+(196×55)=?
Complete the multiplication and the equation becomes
6630+9530=?
The two fractions now have like denominators so you can subtract the numerators.
Then:
66+9530=16130
This fraction cannot be reduced.
The fraction
16130
is the same as
161÷30
Convert to a mixed number using
