Question

chip is a robot that follows commands to move on a number line. this time, the commands include fractions with denominators that are not multiples of each other. for each set of commands, help chip find its new location. command 2: start at $\frac{1}{2}$. move $\frac{1}{7}$ to the left. first, choose a common denominator for $\frac{1}{2}$ and $\frac{1}{7}$. 5 7 9 14

Explanation:

Step1: Find LCM of denominators

Denominators are 2 and 7. LCM(2,7)=14.

Step2: Confirm common denominator

14 is a multiple of both 2 and 7, so it works.
