How do you add a fraction and a whole? Please explain step by step to get marked as brainliest
Dimas [21]

Step-by-step explanation:

How do you add a fraction and a whole number?

add

Whole numbers are all natural numbers including 0.

A fraction represents a numerical value, which defines a part of a whole.

Answer: To add a fraction to a whole number, convert the whole number into a fraction, form a common denominator, and then add the two numerators.

Let's look into the steps to add a fraction to a whole number.

Explanation:

Convert the whole number into a fraction by taking the denominator as 1.

Compare the denominators and make them common so that they become like fractions.

Add the numerators of the two fractions.

Example: Add 2/15 and 5

Step 1: Converting the whole number into a fraction.

5 in terms of a fraction is written as 5/1

Step 2: Make the denominator common.

Since, 2/15 has 15 as the denominator, hence, we need to make the denominator of 5/1 as 15

Multiplying numerator and denominator with 15 we get,

(5 × 15) / (1 × 15) = 75/15

Step 3: Adding the numerators of the two fractions.

2/15 + 75/15 = (2 + 75)/15 = 77/15

Thus, to add a fraction to a whole number, convert the whole number into a fraction, form a common denominator, and then add the two numerators.
