<u>Answer:</u>
Rhonda will not fall 264 times in 360 jumps.
<u>Solution:</u>
Given, The ratio of jumps to falls for ice skater Rhonda is 4 falls to every 15 jumps.
We have to find At this rate, how many times will she not fall in 360 jumps.
Now,
For 15 jumps → 4 falls
For 360 jumps → n falls
Now apply Chris cross method,

So, she falls 96 times in 360 jumps.
