Find four numbers proportional to the numbers 2, 4, 5, and 6 if the difference between the sum of the two last numbers and the sum of the first two numbers is equal to 4.8.
Number 1 wants you to set up proportions so four numbers equal to 2/1 would be: 6/3 8/4 10/5 12/6, and so on. I'm not sure what they're asking when they say the sum of the first two numbers is equal to 4.8
Answer:
The numbers are 1.92
, 3.84
, 4.80
, and 5.76
.
Step-by-step explanation:
Let the numbers be represented by 2x, 4x, 5x, and 6x. Then the given condition says
(6x+5x)-(4x+2x) = 4.8
11x-6x=4.8
5x=4.8
x=.96
Then the numbers are
2x = 1.92
4x = 3.84
5x = 4.80
6x = 5.76
Hope this helps!
