Question

command 1: start at \\(\frac{1}{3}\\). move \\(\frac{1}{4}\\) to the left.
what is a common denominator for \\(\frac{1}{3}\\) and \\(\frac{1}{4}\\)?
12
rewrite the command to show how many twelfths are in each fraction.
new command 1: start at \\(\frac{4}{12}\\). move \\(\frac{1}{12}\\) to the left.

Explanation:

Step1: Find common denominator

The denominators are 3 and 4. LCM(3,4)=12, so common denominator is 12.

Step2: Convert $\frac{1}{3}$ to twelfths

$\frac{1}{3}=\frac{1×4}{3×4}=\frac{4}{12}$

Step3: Convert $\frac{1}{4}$ to twelfths

$\frac{1}{4}=\frac{1×3}{4×3}=\frac{3}{12}$

Step4: Rewrite the command

Start at $\frac{4}{12}$. Move $\frac{3}{12}$ to the left.

Answer:

12; Start at $\frac{4}{12}$. Move $\frac{3}{12}$ to the left.
