Answer 2

Let's solve the expression step by step:

Step 1: Add the fractions inside the parentheses first. 1 3/10 + 1/5

To add fractions, they need to have the same denominator. Convert 1 3/10 to an improper fraction: 1 3/10 = (1 * 10 + 3)/10 = 13/10

Now the expression becomes: 13/10 + 1/5

To add these fractions, find a common denominator, which is 10 in this case: 13/10 + 1/5 = (13/10) + (2/10) = 15/10

Step 2: Next, multiply the result by 4. (15/10) * 4 = 60/10 = 6

Step 3: Finally, subtract 1 1/3 from the previous result. 1 1/3 = (1 * 3 + 1)/3 = 4/3

Now the expression becomes: 6 - 4/3

To subtract fractions, they need the same denominator. Convert 6 to a fraction with a denominator of 3: 6 = 6/1

Now the expression becomes: 6/1 - 4/3

Find a common denominator, which is 3 in this case: 6/1 - 4/3 = (18/3) - (4/3) = 14/3

The final result is 14/3, which is an improper fraction. We can also express it as a mixed number: 14/3 = 4 2/3

So, the final answer is 4 2/3.
