A, B and C are 3 number cards. A is equal to 54. B is twice the size of A. C is one third the size of B. Find the difference between the smallest and greatest numbers.

A = 54

B = 2*54 = 108
C = 108/3 = 36
B-C = 72

To find the difference between the smallest and greatest numbers, we need to determine the values of A, B, and C.

From the information given, we know that:
A = 54
B = 2 * A
C = (1/3) * B

First, let's calculate the value of B:
B = 2 * A
= 2 * 54
= 108

Next, let's find the value of C:
C = (1/3) * B
= (1/3) * 108
= 36

Now we have the values of A, B, and C:
A = 54
B = 108
C = 36

To determine the smallest and greatest numbers, we compare the values of A, B, and C. The smallest number is C (36), and the greatest number is B (108).

Finally, to find the difference between the smallest and greatest numbers, we subtract the smallest number from the greatest number:
Difference = Greatest Number - Smallest Number
Difference = 108 - 36
Difference = 72

Therefore, the difference between the smallest and greatest numbers is 72.

To find the difference between the smallest and greatest numbers, we need to determine the values of A, B, and C.

Given that A is equal to 54, we can substitute this value into the equation to find the values of B and C.

B = 2A
B = 2 * 54
B = 108

C = 1/3 * B
C = 1/3 * 108
C = 36

Now we have the values for A, B, and C:
A = 54
B = 108
C = 36

To find the smallest number, we look for the one with the smallest value, which is C. So, C is the smallest number.

To find the greatest number, we look for the one with the largest value, which is B. So, B is the greatest number.

The difference between the smallest and greatest numbers is calculated as:

Difference = Greatest number - Smallest number
Difference = B - C
Difference = 108 - 36
Difference = 72

Therefore, the difference between the smallest and greatest numbers is 72.
