Answer 12

to figure this out we should find a common divisor. to do this, we should multiply the left fraction by 1 in the form of the divisor of the right fraction and the right fraction by 1 in the form of the divisor of the left fraction. Sounds wordy but its like this:
\[\frac{12}{12}\times\frac{7}{9}-\frac{9}{9}\times\frac{5}{12}\]after this we have everything in terms of the same base, and we can write it like this: \[\frac{84-45}{108}=\frac{39}{108}\]which reduces down to 13/36

Parentheses
Equations
Multiplication
Division
Addition

This is order of operations.

Answer 71

Parentheses
Equations
Multiplication
Division
Addition

Answer 72

the ( ) s are parentheses. So we handle them first.

Answer 73

1/2 + 1/3 = 5/6. So we can simplify down to 5/6 times 7/5

Answer 74

Theres no equations, so we go to multiplication.

Answer 75

5/6 Times 7/5 is 2 and 7/30. So theres your answer.
2 7/30

Answer 76

reduce 14 1/24
