**Write your answers in simplest form.**

Question 1.

\(\frac{4}{12}\) + \(\frac{4}{12}\) = ___________

Answer:

The Denominators of the given fractions are same so add the numerators.

4/12 + 4/12 = 8/12 = 2/3.

Question 2.

\(\frac{4}{5}\) – \(\frac{2}{5}\) = ____________

Answer:

The Denominators of the given fractions are same so Subtract the numerators.

4/5 – 2/5 = 4-2/5 = 2/5.

Question 3.

\(\frac{6}{10}\) + \(\frac{2}{10}\) = _____________

Answer:

The Denominators of the given fractions are same so add the numerators.

6/10 + 2/10

= 6 + 2/10

= 8/10

= 4/5.

Question 4.

\(\frac{2}{4}\) + \(\frac{1}{4}\) = _____________

Answer:

The Denominators of the given fractions are same so add the numerators.

2/4 + 1/4 = 2+1/4

= 3/4.

Question 5.

\(\frac{4}{7}\) – \(\frac{1}{7}\) = ______________

Answer:

The Denominators of the given fractions are same so subtract the numerators.

4/7 – 1/7

= 4-1/7

= 5/7.

Question 6.

\(\frac{2}{8}\) + \(\frac{5}{8}\) = ______________

Answer:

The Denominators of the given fractions are same so add the numerators.

2/8 + 5/8

= 5 + 2/8

= 7/8

Question 7.

\(\frac{3}{5}\) + \(\frac{1}{5}\) = ______________

Answer:

The Denominators of the given fractions are same so add the numerators.

3/5 + 1/5

= 3+1/5

= 4/5

Question 8.

\(\frac{6}{9}\) + \(\frac{2}{9}\) = _______________

Answer:

The Denominators of the given fractions are same so add the numerators.

6/9 + 2/9

= 6 + 2/9

= 8/9

Question 9.

\(\frac{1}{11}\) + \(\frac{1}{11}\) = _______________

Answer:

The Denominators of the given fractions are same so add the numerators.

1/11 + 1/11

= 1 + 1/11

= 2/11

Question 10.

Steve, Gabe, and Lena are decorating a wall. Steve decorates \(\frac{3}{7}\) of the wall, Gabe decorates \(\frac{1}{7}\), and Lena decorates \(\frac{3}{7}\). How much more of the wall do they have to decorate?

Answer:

Steve decorates \(\frac{3}{7}\) of the wall.

Gabe decorates \(\frac{1}{7}\) of the wall.

Lena decorates \(\frac{3}{7}\) of the wall.

The Denominators of the given fractions are same so add the numerators.

3/7 + 1/7 + 3/7 = 3+3+1/7

= 7/7 = 1

They have decorating 1 of the wall.
