Lesson 3 Summary
The size of the unit we usage to measure somepoint affects the measurement.
If we meacertain the exact same amount through various devices, it will take even more of the smaller sized unit and fewer of the larger unit to expush the measurement. For instance, a room that procedures 4 yards in length will measure 12 feet.
Tbelow are 3 feet in a yard, so one foot is frac13 of a yard.It takes 3 times as many type of feet to measure the very same size as it does with yards.It takes frac13 as many yards to meacertain the very same size as it does via feet.
