Answer 2

Concept:

Mathematics has 4 basic operations namely edition subtraction multiplication and division. Simplifying and expression means solving the expression to reduce it into its lowest form.

Given:

We are given the expression:

3 / 5 + 2 / 15 + 7 / 10​.

Find:

We need to find the sum of the expression.

Solution:

We will first calculate its LCM:

LCM of 3, 15 and 10 = 3 × 5 × 2 = 30.

Now we will make them into like fractions:

3 / 5 = 3 / 5 × 6  /6 = 18 / 30

2 / 15 = 2 / 15 × 2 / 2 = 4 / 30

7 / 10 = 7 / 10 × 3 / 3 = 21 / 30

Now adding them, we get:

18 / 30 + 4 / 30 + 21 / 30 = 43 / 30.

Therefore, the sum of the expression is 43 / 30.
