Question

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.

Answer 1

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 2

The numbers are 1.92 , 3.84 , 4.80 , and 5.76 .

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!
