Question

Three numbers are in the ratio 3:4:5. The sum to of largest and smallest is 84 added to the third. find the numbers.​

Answer 1

Step-by-step explanation:

Let the numbers be 3x, 4x and 5x

Sum of largest and smallest number = 84

5x + 3x = 84

8x = 84

x = 84/8

x = 10.5

Hence, the numbers are:

3x = 3*10.5 = 31.5

4x = 4*10.5 = 42

5x = 5*10.5 = 52.5

Answer 2

Answer:

The largest number = 5

The smallest number = 3

So, 5x+3x = 84

8x = 84

x = 84/8

x = 10.5

So , 3x = 3 multiply 10.5

= 31.5

4x, = 4 multiply 10.5

= 42.0

5x = 5 multiply 10.5

= 52.5
