(3 ft/yd)

If you have yd

(15 ft)(16 ft) = 15*16 ft

Units can be multiplied and divided just as any other algebraic entity. Sometimes it helps to keep the units with the numbers, just so the units are kept straight. Conversion from one set of units to another should be thought of as a multiplication (or division) by 1 (one).

3 ft and 1 yd are exactly the same thing, just expressed in different units. So, dividing one by the other gives you a value of 1 (one). You can multiply by 1 without changing a thing. The same is true of dividing by 1. If I have 240 ft

^{2}= 9 ft^{2}/yd^{2}.If you have yd

^{2}, you can multiply by the fraction above to get ft^{2}. If you have ft^{2}, you can divide by the fraction above to get yd^{2}.(15 ft)(16 ft) = 15*16 ft

^{2}= 240 ft^{2}= 240 ft^{2}/(9 ft^{2}/yd^{2}) = 26.67 yd^{2}.Units can be multiplied and divided just as any other algebraic entity.

^{2}, and I multiply by 1 = (1 yd^{2})/(9 ft^{2}), I still have 240 ft^{2}, but now expressed as 26.67 yd^{2}.
