Answer 2

To solve the given expression, let's take it step by step:

1. 1 1/5:1/5: This can be simplified as follows: 1 + 1/5 ÷ 1/5 = 1 + 1 = 2

2. 2 1/2:1 2/3: This can be simplified as follows: 2 + 1/2 ÷ 1 + 2/3

To divide fractions, we need to invert and multiply, so: 2 + 1/2 ÷ 1 + 2/3 = 2 + 1/2 * 3/2 + 2/3

Now, we find a common denominator for 2 and 3, which is 6: 2 + 1/2 * 3/2 + 2/3 = 2 + 3/4 + 4/6

Now, convert all the fractions to have the same denominator: 2 + 3/4 + 4/6 = 2 + 9/12 + 8/12

Now add the whole numbers and fractions separately: 2 + 9/12 + 8/12 = 2 + (9 + 8)/12 = 2 + 17/12

Now, if we convert the mixed number to an improper fraction: 2 + 17/12 = (2 * 12 + 17)/12 = 41/12

3. 1 1/5*1/6: This can be simplified as follows: 1 + 1/5 * 1/6

Now, multiply the fractions: 1 + 1/5 * 1/6 = 1 + 1/30

4. 1 12* 1 13: This expression is not clear, as there seem to be multiple operators in it. Please clarify the expression, so I can help you solve it accurately.

Overall, the simplified expressions are as follows:

1. 1 1/5:1/5 = 2
2. 2 1/2:1 2/3 = 41/12
3. 1 1/5*1/6 = 1 + 1/30
