Final answer:
To show that 20 is four times as much as 5, use the equation 5 × 4 = 20, which means combining four groups of five objects each to get 20 objects.
Step-by-step explanation:
To represent that 20 is four times as much as 5, we can use a simple multiplication model. The equation to represent this relationship is 5 × 4 = 20. This means that if you have the number 5 and multiply it by 4, you will get 20. To visualize this, think of having four groups of five objects each. When you combine them together, you will have a total of 20 objects. This demonstrates that 20 is indeed four times as much as 5. In mathematical terms, we refer to the number 4 as the 'multiplier' or 'factor' because it is the number that five is being multiplied by to achieve the product of 20
