3/4+(1/4-1/6)= show work adding and subtracting fractions​
Fittoniya [83]

Answer:

5/6

Step-by-step explanation:

<u>Step 1:  Make all fractions have same denominator:  24</u>

3/4 * 6/6 = 18/24

1/4 * 6/6 = 6/24

1/6 * 4/4 = 4/24

<u>Step 2:  Plug in the new fractions into the old place</u>

3/4 + (1/4 - 1/6)

18/24 + (6/24 - 4/24)

<u>Step 3:  Solve inside parenthesis</u>

18/24 + (6/24 - 4/24)

18/24 + 2/24

<u>Step 4:  Add</u>

18/24 + 2/24

20/24

<u>Step 5:  Simplify</u>

20/24

10/12

Answer:  5/6
