What do we get? This is going to be equal to pi times, see our least common multiple looks like 6. We're going to put everything over a denominator of 6. 8 is the same thing as 48 over 6. 32 over 3 is the same thing as 64 over 6, so minus 64 over 6. 4 is the same thing as 24 over 6. 1 half is the same thing as 3 over 6, so this is negative 3 over 6, the same thing as negative 1 half.
