Is there a shortcut to find $39\%$ of $234$? One way is to find $\frac{39}{100}\times234$. This involves multiplying decimal numbers. Second way is find $10\%$ which is $23.4$, and then $40\%$ which is $93.6$ and subtract $1\%$ which is $2.34$.
What I would like to know is there any other quicker way?
Thanks
