Nathan's lawnmower uses 2 3 of a tank of gas to cut three one-act lawns How many one-armed lawns can he cut with a full tank of gas Explain?

To determine how many one-act lawns Nathan can cut with a full tank of gas, we first find the gas used per lawn. Nathan uses ( \frac{2}{3} ) of a tank for three lawns, so the gas used per lawn is ( \frac{2}{3} \div 3 = \frac{2}{9} ) of a tank. With a full tank, he can cut ( 1 \div \frac{2}{9} = \frac{9}{2} = 4.5 ) one-act lawns. Therefore, Nathan can cut 4 one-act lawns completely with a full tank of gas.
