Answer:

1. ½ + ½ = ²/2 = 1

2. ⅝ - ⅜ = ²/8 = ¼

Step-by-step explanation:

Rationals are can take the form of a fraction or decimals.

They are part of a whole.

In add or subtracting Rationals having the same denominator, the operation seems easy and fast.

Let's consider some examples:

ADDITION OF RATIONALS

1. ½ + ½ = ²/2 = 1

How:

In Working with Rationals having thesame denominator, you take the sum of the NUMERATOR and pick just one of the DENOMINATOR.

NUMERATOR: 1+1 = 2.

DENOMINATOR: 2

Operations: 2 ÷ 2 = 1.

2. ⅜ + ⅞ = 10 / 8

How:

2

Numerator: 3+7 = 10

Denominator: 8

Operations : 10/8 = 5/4

SUBTRACTION:

1. ⅝ - ⅜ = ²/8 = ¼

How:

Numerator: 5-3 = 2

Denominator: 8

Operations = 2/8 = ¼

2. ¾ - ¼ = ²/4 = ½

How:

Numerator: 3-1 = 2

Denominator: 4

Operations : ²/4 = ½

Enjoy mathematics!
