Question

4⁄8 + ¼ = ? What is the correct answer to this problem? a. 1 b. ⅝ c. ¾ d. 2⁄8

Answer 1

c. ¾

Explanation:

By adding fractions, you must follow the following steps:

1. Make sure the numbers of the denominators are equal.

2. Add the numerators and put this number over the denominator.

3. Simplify.

Since the number of the denominators are different. We must multiply and divide one fraction for a number such that the denominators stand equal. For instance, we can multiply and divide fraction 1/4 by number 2 as follows:

`(1)/(4)=(1 * 2)/(4 * 2)= (2)/(8)`

So the expression can be written as follows:

`(4)/(8)+(2)/(8)=(6)/(8) \\ \\ But \ (6)/(8) \ can \ be \ written \ as: \\ \\ (3 * 2)/(4 * 2) = \boxed{(3)/(4)}`
