A: smallest
c: largest
b: third
a+b+c=180
a=c/3
b=10+a
solve it
a=34
b=44
c=102
Find the common denominator for both unlike fractions.
EX: 1 2
12 8
The lowest common factor is both fractions is 24. Multiply both denominators to get 24.
Do not forget to multiply the numerators with the number you used to multiply the denominators together.
You do not have to multiply each side by the same number.
