Question

5.) ryan spent 78.2 minutes watching 59 tiktok videos that were all about the same length. approximately how many minutes did ryan spend watching each video?

Explanation:

Step1: Set up the division formula

To find the time per video, divide total time by number of videos. The formula is \( \frac{78.2}{59} \).

Step2: Approximate the values

Approximate \(78.2\approx80\) and \(59\approx60\). Then the formula becomes \( \frac{80}{60}=\frac{4}{3}\approx1.33\).
Another way: \(78.2\div59 = 1.32542373\approx1.33\) (using calculator - like division process: \(59\times1 = 59\), \(78.2-59=19.2\), \(59\times0.3 = 17.7\), \(19.2 - 17.7=1.5\), \(59\times0.02=1.18\), \(1.5 - 1.18 = 0.32\), \(59\times0.005=0.295\) etc. and sum up \(1+0.3 + 0.02+0.005\approx1.33\)).

Answer:

Approximately \(1.33\) minutes.
