Answer 1

1. 5/12 + 2/15 = 25/60 + 8/60 = 33/60 = 11/20

2. 11/20 * 3 7/11 = 11/20 * 40/11 = 40/20 = 2

Ответ: 2

Answer 2

Let's solve the expression step by step:

Step 1: Add the fractions 5/12 and 2/15. To add fractions, we need to find a common denominator. The least common multiple (LCM) of 12 and 15 is 60.

(5/12) + (2/15) = (5/12)(5/5) + (2/15)(4/4) = 25/60 + 8/60 = (25 + 8)/60 = 33/60

Step 2: Multiply the result from Step 1 by 3 7/11. To multiply a whole number and a mixed fraction, first, convert the mixed fraction to an improper fraction.

3 7/11 = (3 * 11 + 7)/11 = 40/11

Now, multiply:

(33/60) * (40/11) = (33 * 40) / (60 * 11) = 1320 / 660 = 2

So, the final result of the expression is 2.
