\( 9 \times 1 \frac{4}{5} \) will be

To solve \( 9 \times 1 \frac{4}{5} \), first convert the mixed number to an improper fraction. The mixed number \( 1 \frac{4}{5} \) can be changed to \(\frac{9}{5}\) (since \(1 \times 5 + 4 = 9\)). Now multiply: \( 9 \times \frac{9}{5} = \frac{81}{5} \), which can also be expressed as \( 16 \frac{1}{5} \) when converted back to a mixed number. So, your final answer is \( 16 \frac{1}{5} \)! If you ever find yourself needing to multiply a whole number and a mixed number, remember that converting the mixed number to an improper fraction is usually the easiest route. This way, you can avoid the hassle of splitting up the calculations. Just multiply straight through and convert back, if necessary! And a common mistake? Sometimes, people forget to convert the whole number to a fraction too! You can think of it as \( \frac{9}{1} \). It makes it a lot easier to visualize the multiplication, trust me!
