Question

1. 3/4 + 5/6 + 1/4 + 1/62. 3/4 + 1/4 +5/6 +1/6

Answer 1

1. 3/4 + 5/6 + 1/4 + 1/6

The first step is to find the lowest common multiple(LCM) of the numbers in the denominators. The LCM is 12. We would divide each denominator by 12 and multiply the result by the numerator. The common denominator would be 12. Thus, we have

(3 * 3 + 5 * 2 + 1 * 3 + 1 * 2)/12

= (9 + 10 + 3 + 2)/12

= 24/12

= 2
