Why is it important to understand the comparison of two numbers as a ratio?
Using a ratio to compare quantities is different from using subtraction to find the difference between quantities because a ratio tells you the value of one quantity for a given value of the other quantity.
Why do we need to compare different quantities?
In math, to compare means to examine the differences between numbers, quantities or values to decide if it is greater than, smaller than or equal to another quantity. By comparing, we can define or find by how much a number is greater or smaller. Here’s how we can also compare decimals and fractions.
Where is ratio used in real life?
