Question

A chain has a ribbon tied to it every 2/3 foot. If the chain is 10 2/3 feet long, how many ribbons are tied to the chain??

Answer 1

Answer:

16 ribbons

Step-by-step explanation:

Given the length of the chain as 10$\frac{2}{3}$ and there is a ribbon tied to it every $\frac{2}{3}$, we can take the total length of the chain and divide by the measure of $\frac{2}{3}$:

$10\frac{2}{3}=\frac{32}{3}$

$\frac{\frac{32}{3}}{\frac{2}{3}}=\frac{32}{3}*\frac{3}{2}=\frac{96}{6}=16$

When dividing with fractions, we use the rule of 'keep/change/flip' to keep the first fractions, change the operation to multiplication and flip the second fraction.
