Answer:
Let the number be x
The expression above is written as
15x² = 20x
Divide both sides by x
We get
15x²/x = 20x/x
15x = 20
Divide both sides by 15
x = 20/15
x = 4/3

Answer:
36x
Step-by-step explanation:
You do 12 x 3 which equals 36. Then you add the x at the end.
4¹/₂ × ⁶/₁₇
⁹/₂ × ⁶/₁₇
²⁷/₁₇
1¹⁰/₁₇
The product of 4¹/₂ and ⁶/₁₇ will be smaller than 4¹/₂.
