Give all possible proportions using the numbers 2 5 8 and 20
1 answer:
Answer:
Step-by-step explanation:
Proportions are fractions that can be created using the numbers given. Let's pair each and reduce if possible.
Starting with 2:
2/5
2/8 = 1/4
2/20 = 1/10
Then 5:
5/2
5/8
5/20 = 1/4
Then 8:
8/2 = 4/1
8/5
8/20 = 2/5
Lastly 20:
20/2 = 10/1
20/5 = 4
20/8 = 5/2
So, we can see some are repeating, hence the unique proportions are:
2/5, 1/4, 1/10, 5/2, 5/8, 4/1, 8/5, 10/1

We want to change the digit in the number 5,341 into 5,841, and to find the difference between the numbers.
Refer to the figure shown below.
The number 3 is in the 3rd place (hundreds) of the number 5,341 as a digit.
It is replaced by 8 to form the number 5,841.
This means that 300 is replaced by 800 because, in the third place, we count by hundreds in the 3rd place.
The difference between 800 and 300 is 500.
Subtraction of 5,341 from 5,841 also yields 500.
