To solve this expression, we need to follow the order of operations which is PEMDAS (parentheses, exponents, multiplication/division, addition/subtraction).
First, let's simplify the expression within the parentheses: 7/12 - 1/2 = 7/12 - 6/12 = 1/12
Now, we substitute this back into the original expression: 3/20 * 1/12 + 79/80
Next, we multiply the fractions: 3/20 * 1/12 = 3/240 = 1/80
Finally, we add the result to 79/80: 1/80 + 79/80 = 80/80 = 1
Therefore, the final result of the expression 3/20*(7/12-1/2)+79/80 is 1.
