Hi Ed,

When you add or subtract fractions it is really helpful to have the same denominator. You have denominators of 10, 2 and 5 so a common denominator would be 10. Write an equivalent fraction to $\large \frac32$ with denominator 10, write an equivalent fraction to $\large \frac65$ with denominator 10, and write the missing fraction as $\large \frac{?}{10}.$ Substitute these into the original equation. What is the value of "?"?
