Question

Determine the number of ice cubes in 32 glasses at a rate of 20 ice cubes in 5 glasses.

Answer 1

What We know
20 Ice cubes in every 5 glasses
20:5
Solution
20 / 5 = 4
5 / 5 = 1
4 ice cubes for every 1 glass
1 x 32 = 32
4 x 32 = 128
ANSWER: 128 ice cubes in every 32 glasses

Answer 2

The answer is 128 ice cubes.

Explanation:

In order to determine the answer, we have to know about rates.

A rate is just a fraction that describes the relation between two measures.

In this case, we have the measure "ice cubes" and the measure "glasses".

The rate is :

`(icecubes)/(glasses)=(20)/(5)`

Then, we always have to fulfil this rate. So, for 32 glasses, we need:

x=amount of ice cubes

`(x)/(32)=(20)/(5)  \\\\x=(20*32)/(5) \\\\x=128`

Finally, there are 128 ice cubes for 32 glasses.
