36 is equal to 45% of a number n. Write and solve an equation to find n. Write the percent as a decimal.
Equation=?
n=?
My friend and I are both stumped on this question.
To write and solve an equation to find the value of n, we first need to translate the given information into mathematical language.
We are told that 36 is equal to 45% of a number n. To write 45% as a decimal, we divide 45 by 100:
45% = 45/100 = 0.45
Now, we can set up the equation:
0.45n = 36
To find the value of n, we need to isolate n on one side of the equation. To do this, we divide both sides of the equation by 0.45:
(0.45n) / 0.45 = 36 / 0.45
Simplifying the equation:
n = 36 / 0.45
Dividing 36 by 0.45, we find:
n = 80
Therefore, the value of n is 80.
0.45n = 36
n = 36/0.45
n = 80
