Verified Answer :

You can actually \(multiply\) and \(add\)  to find your \(answer\) like this → \(15(10) + 4\)

So, let's solve this problem: 

\(10\) is still your \(denominator\) since we kept that as that 

Now we have to find the \(numerator\)

\(15(10) = 150 \\ 150 + 4 = 154\)

Our \(numerator\) would mostly be: \(154\)

So, \(15 \frac{4}{10}\) as a \(whole\) \(number\) would most likely \(be\) →\(\frac{154}{10}\)

Good luck on your assignment and enjoy your day!
