Two third of the number is 12, if the same number is subtracted from 38. What is the difference?
To find the difference, we need to determine the value of the number. Let's set up an equation based on the given information:
Two-thirds of the number = 12
Let's denote the number as "x". We can express two-thirds of the number as (2/3)x:
(2/3)x = 12
To isolate x, we can multiply both sides of the equation by the reciprocal of (2/3), which is (3/2):
x = 12 * (3/2)
Simplifying the right side of the equation:
x = 18
Now that we know the value of the number, we can determine the difference when it is subtracted from 38:
Difference = 38 - x
Substituting x = 18:
Difference = 38 - 18
Difference = 20
Therefore, the difference when the number is subtracted from 38 is 20.
well, 2/3 n = 12, so n = 18
now subtract
