Question

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

Answer 1

1/4 + 2/7 + 1/2

Find a number that 4,7, and 2 have in common

List the multiples o 4,7, and 2

4,8,12,15,20,24,28,32,36,40

7,14,21,28,35,42,49,56,63,70

2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40

4,7,and 2 all have 28 so 28 is the common denominator

1/4 = 1/4 x 7/7 = 7/28

you can multiply because 7/7 = 1 so you are just multiplying by 1

2/7 x 4/4 = 8/28

1/2 x 14/14= 14/28

7/28 + 8/28 + 14/28 = 29/28 or 1 1/28

Hope this helps

Answer 2

Hey there! :)

Answer:

29/28.

Explanation:

Starting with:

`(1)/(4) + (2)/(7) + (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:

`(7)/(28) + (8)/(28) + (14)/(28) =`

Add the fractions:

`(7)/(28) + (8)/(28) + (14)/(28) = (29)/(28)`

Therefore, the fractions sum up to 29/28.
