Question

What is 1 half subtract 1 tenth

Answer 1

To solve for $\frac{1}{2}- \frac{1}{10}$ You first need to find a common denominator.

To do so, you need to make both denominators 10 by multiplying the top and bottom of $\frac{1}{2}$ by 5

$\frac{5}{10}- \frac{1}{10}$=$\frac{4}{10}$    Reduce by dividing both the top and bottom by 2

Your answer is $\frac{2}{5}$
