Order the fractions from least to greatest: 2/3,5/6,29/36,8/9. Briefly explain your method.

Answer: 2/3, 29/36, 5/6, 8/9

Step-by-step explanation:

You find the common denominator you could use for all fractions. In this instance, you can use 36 for the common denominator.

2/3: 36/3=12, 2x12=24 therefore 2/3 becomes 24/36.

29/36: you leave this one alone, it has already been simplified.

5/6: 36/6=6, 6x5=30 therefore 5/6 becomes 30/36.

8/9: 36/9=4, 8x4=32 therefore 8/9 becomes 32/26.

3x - 20 = 4 PLEASE EXPLAIN HOW YOU GOT THE ANSWER IN STEPS!

Answer:

x = 8

Step-by-step explanation:

3x - 20 = 4

add 20 to both sides

3x - 20 + 20 = 4 + 20

3x = 24

divide both sides by 3

$\frac{3x}{3}$ = $\frac{24}{3}$

x = 8
