1/2+ 1/4
= 2/4+ 1/4
= 3/4

1/12+ 1/6
= 1/12+ 2/12
= 3/12
= 1/4

Therefore, 1/4+ 1/6+ 1/12
= (1/12+ 1/6)+ (1/12+ 1/6)
= 2*(1/12+ 1/6)
= 2* (1/4)
= 2/4
= 1/2

Hope this helps~

In order to add fractions, they need common denominators
1/2 * 2 = 2/4 + 1/4 = 3/4
1/6 * 2 = 2/12 + 1/12 =3/12, divide by 3 to reduce = 1/4
1/4 * 3, 1/6 * 2 = 3/12 + 2/12 + 1/12 = 6/12, divide by 6 to reduce = 1/2

What is the solution to the inequality shown below?

lesantik [10]

To solve the inequality, you need to isolate/get the variable "p" by itself in the inequality:

5p + 26 < 72 Subtract 26 on both sides

5p + 26 - 26 < 72 - 26

5p < 46 Divide 5 on both sides to get "p" by itself
