Evaluating Expressions with Fractions

In this article, we will evaluate an expression that involves fractions, multiplication, and addition. The expression is:

1/2 × 45 + 0.5 × 37 + 5 1/10 × 18

To evaluate this expression, we need to follow the order of operations (PEMDAS):

1. Simplify fractions: Convert mixed fractions to improper fractions.
2. Multiply fractions with integers: Multiply the fractions with integers.
3. Add the results: Add the results of the multiplications.

Let's break down the expression step by step:

Simplify fractions

• 1/2 is already a simple fraction.
• 0.5 is equal to 1/2.
• 5 1/10 can be simplified to 51/10.

So, the simplified expression is:

(1/2) × 45 + (1/2) × 37 + (51/10) × 18

Multiply fractions with integers

• (1/2) × 45 = 22.5
• (1/2) × 37 = 18.5
• (51/10) × 18 = 92.58

Add the results

Now, let's add the results of the multiplications:

22.5 + 18.5 + 92.58 = 133.58

Therefore, the final result of the expression is 133.58.
