<span>Ivy has 4 tiles with pictures of plants and 5 tiles with pictures of animals. Ivy keeps all the tiles on a mat with the pictures hidden and mixes them up. She then turns one tile face up and finds the picture of a plant on it. She removes this tile from the mat and turns another over tile without looking. What is the probability that the second tile that Ivy turns over has a plant on it. To solve the problem the first step is to find out how many tiles are in total. Since one of the plant tiles were removed we have 3 left. 
</span>
5 + 3 = 8

Now we find the percent by dividing 3 from 8. The top number is called  the NUMERATOR<span> and the bottom number is called the </span>DENOMINATOR<span>.</span>

3 ÷ 8 = 0.375

0.375 x 100 = 37.5

Answer = <span>37.5%

Answer: There are 195 miles Reggie ran over the 60 days period.
