Inessa05 [86]

<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,

15 \times n=360 \times 4 \rightarrow n=\frac{360 \times 4}{15}=24 \times 4=96

So, she falls 96 times in 360 jumps.

Then, number of times she will not fall = 360 jumps – 96 falls = 264 times.

Hence, Rhonda will not fall 264 times in 360 jumps.
