Answer 2

To solve the expression 1 3/10 + (4 + 2 1/3), we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

Let's break down the expression step by step:

1 3/10 + (4 + 2 1/3)

First, let's simplify the addition inside the parentheses:

4 + 2 1/3 = 4 + 7/3

To add these two fractions, we need to find a common denominator. The common denominator for 3 and 1 is 3, so we can rewrite the expression as:

4 + 7/3 = 4 + (7/3 * 3/3) = 4 + 21/3

Now, we can add the whole numbers and the fractions separately:

4 + 21/3 = 4 + 7 = 11

Next, let's add the whole number and the fraction outside the parentheses:

1 3/10 + 11

To add these two numbers, we need to find a common denominator. The common denominator for 10 and 1 is 10, so we can rewrite the expression as:

1 3/10 + 11 = (1 * 10 + 3)/10 + 11 = 13/10 + 11

Now, we can add the fractions:

13/10 + 11 = (13 + 110)/10 = 123/10

Therefore, the result of the expression 1 3/10 + (4 + 2 1/3) is 123/10.
