Number of gumdrops = 420
Number of chocolate bars = 280
Total Number of candies = 700
To find:
The ratio of candies to chocolate bars = ?
Solution:
First of all, let us discuss the method to find the ratio of any two quantities.
Suppose, we need to find the ratio of two numbers and
.
Then to find the ratio , we need to divide p by q and represent it in the simplest form
such that a and b can not be divided further.
Here, to find the ratio of candies to chocolate bar:
Here, we can simplify the fraction by dividing the numerator and denominator by 10 first:
Now, let us divide the numerator and denominator by 14:
So, the ratio is <em>5 : 2</em>
