A bag has 30 tiles, numbered 1-30. Write the ratio even tiles to odd tiles in simplest form.

guapka [62]

Answer:

r=1

Step-by-step explanation:

<u>Ratio of Values </u>

A ratio compares two values by diving them. If the ratio is greater than one, then the value in the numerator is greater than the value in the denominator. The opposite relation gives ratios lower than 1. A ratio of 1 means both values are the same

We have a set of tiles numbered 1 to 30:

1,2,3,4,5,6...,29,30

Note that each odd-numbered tile is followed by an even-numbered tile. It means we have 15 odd tiles and 15 even tiles. The ratio is

$\displaystyle r=\frac{even}{odd}$

$\displaystyle r=\frac{15}{15}$

r=1
