Add. Simplify (or reduce) your answer, if necessary 1/4 +2/7+1/2=

Bumek [7]

Hey there! :)

Answer:

29/28.

Step-by-step explanation:

Starting with:

$\frac{1}{4} + \frac{2}{7} + \frac{1}{2} =$

Begin by finding a common denominator. A number that contains all of the denominators as a factor would be 28. Change each fraction to contain a denominator of 28:

$\frac{7}{28} + \frac{8}{28} + \frac{14}{28} =$

Add the fractions:

$\frac{7}{28} + \frac{8}{28} + \frac{14}{28} = \frac{29}{28}$

Therefore, the fractions sum up to 29/28.

15 POINT 1 QUESTION<br> ITS ALL UP TO YOU!!!!

Anni [7]

First, we can simplify the left side. (6+8x)/2 is equal to 3 + 4x. We can put the equation together at this point.

3 + 4x = 5x

we can subtract 4x from both sides to get our final answer,

3 = x, or x = 3. :)
