10.5:1/16 im stuck on finding this answer

Just multiply 10.5 with 16. When you divide a number with a fraction, you can switch it's denominator and numerator then multiply it with the first number to obtain the right result. Youw will then get 168 as the answer.

I am not sure if this is correct but I converted the fraction into a decimal and I got 0.0625 and after that I devided 10.5 and 0.0265 and I got 168
