Question

What is the sum of the following equation?

3/10 + 39/100=

Answer 1

69/100

Explanation:

3/10 + 39/100

In order to find the sum of this equation, you must first identify the least common denominator.

10: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120

100: 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200

The lowest number 10 and 100 have in common is 100.

Second, we must make both fractions have a denominator of 100.

**MULTIPLY THE NUMERATOR AND DENOMINATOR BY THE SAME THINGS!!**

3/10 x 10/10 = 30/100

39/100 x 1/1 = 39/100

Lastly, we add the new fractions.

30/100 + 39/100 = 69/100

69/100 is already in the simplest form.

Therefore, 3/10 + 39/100 = 69/100

Answer 2

69/100

Explanation:

You need to make the denominators equal, so multiply 10 by 10, which makes 100. Whatever you do to the denominator, do to the numerator.

30/100 + 39/100 = 69/100
