Question
If th of a number is 6 more than the number, then what is the number?
a. -20
b. 20
c. -60
d. 60
Solution
Let's solve this step by step:
-
Let's assume the number is x.
-
According to the problem, 2/5th of the number is 6 more than 1/2 of the number. We can write this as an equation: 2/5x = 1/2x + 6
-
To solve for x, we first need to get rid of the fractions. We can do this by multiplying every term by 10: 4x = 5x + 60
-
Next, we subtract 5x from both sides of the equation: -x = 60
-
Finally, we multiply both sides by -1 to solve for x: x = -60
So, the number is -60. The correct answer is c. -60.
