Question

x/3+x/4+x/6= 180


pls answer fasst and in detail
​

Answer 1

Answer:

x=240

Explanation:

First get their LCD, which is equal to 12

so:

12÷3=4

12÷4=3

12÷6=2

it will turn out like this:

x/3=4x/12

x/4=3x/12

x/6=2x/12

add those fractions:

4x+3x+2x 9x 3x

------------ = ----- = ------- = 0.75x

12 12 4

*I simplified the fraction and converted it into decimal for easier process, but both fraction and decimal will still end up with the same answer

so let's say:

0.75x=180

x=180÷0.75

x=240

For checking:

(240x4)÷12=80

(240×3)÷12=60

(240×2)÷12=40

80+60+40=180

Therefore, our answer, 240, is correct.
