Answer:
Step-by-step explanation:
[tex]p\%=\dfrac{p}{100}\\\\15.1\%=\dfrac{15.1}{100}=0.151\\\\n-\text{a number}\\\\15.1\%\ \text{of}\ n\ \text{is}\ 10.4\Rightarrow0.151n=10.4\qquad\text{divide both sides by 0.151}\\\\\dfrac{0.151n}{0.151}=\dfrac{10.4}{0.151}\\\\n\approx68.87[/tex]
68.87 approx
Let the number be n, and transform the percentage 15.1% into the decimal fraction 0.151.
Then 0.151n = 10.4.
Dividing both sides by 0.151 to isolate n, we get:
n = 10.4/0.151 = 68.87 approx
