Answer
48 is 30% of 160. The unknown number is 160.
Work Step by Step
Let's translate these words into mathematical language. We are trying to look for the unknown number, $x$.
48 = 30%$\times x$
We change 30% into a decimal by changing the % symbol into a decimal and moving that decimal two places to the left.
We then get:
48 = 0.30$\times x$
Now we can solve for $x$.
We divide each side by 0.30, and we get:
$x = 160$
