Hello! i struggle with math a lot so if u guys can me with these questions with the work i would appreciate a lot

Exercise #1 = ³/₄

Exercise #3 = ¹/₂

Exercise #5 = 1 ¹/₉

Exercise #7 = ²/₅

Exercise #9 = ¹¹/₁₅

Step-by-step explanation:

When adding or subtracting fractions, you always have to find a common denominator first.

Exercise #1

⁵/₈ + ¹/₈

In this exercise, we already have the common denominator 8. Next, add the numerators together.

⁵/₈ + ¹/₈ = ⁶/₈

From here, we can simplify the fraction by dividing both the numerator and the denominator by 2.

6 ÷ 2 = 3

8 ÷ 2 = 4

This is as simplified our answer can get since there are no more common factors between the numerator (3) and the denominator (4).

⁶/₈ = ³/₄

Exercise #3

-¹/₄ + ³/₄

In this exercise, we already have the common denominator 4. Next, add the numerators together. (In this exercise, the numerators are -1 and 3. When adding a negative number, you can think of the equation as: 3 - 1 = 2)

-¹/₄ + ³/₄ = ²/₄

From here, we can simplify the fraction by dividing both the numerator and the denominator by 2.

2 ÷ 2 = 1

4 ÷ 2 = 2

This is as simplified our answer can get since there are no more common factors between the numerator (1) and the denominator (2).

²/₄ = ¹/₂

Exercise #5

⁵/₉ + ⁵/₉

In this exercise, we already have the common denominator 4. Next, add the numerators together.

⁵/₉ + ⁵/₉ = ¹⁰/₉

From here, we can simplify the fraction by turning it into a mixed number. To do this, we can subtract 9 from the numerator because 9 is the denominator and ⁹/₉ = 1. From this, we can determine that our simplified answer is:

¹⁰/₉ = 1 ¹/₉

Exercise #7

³/₁₀ + ¹/₁₀

In this exercise, we already have the common denominator 10. Next, add the numerators together.

³/₁₀ + ¹/₁₀ = ⁴/₁₀

From here, we can simplify the fraction by dividing both the numerator and the denominator by 2.

4 ÷ 2 = 2

10 ÷ 2 = 5

This is as simplified our answer can get since there are no more common factors between the numerator (2) and the denominator (5).

⁴/₁₀ = ²/₅

Exercise #9

⁷/₁₅ + ⁴/₁₅

In this exercise, we already have the common denominator 15. Next, add the numerators together.

⁷/₁₅ + ⁴/₁₅ = ¹¹/₁₅

This is as simplified our answer can get since there are no more common factors between the numerator (11) and the denominator (15).

~Hope this helps!~

it could be a ..idk tho

d is correct
