Final answer:
To find the number of pieces Yoon cuts, divide the length of the plywood by the length of each piece. In this case, Yoon cuts 6 pieces.
Step-by-step explanation:
To find the number of pieces Yoon cuts, we need to divide the length of the plywood by the length of each piece. Yoon has a plywood piece that is (2)/(3) yards long, and each piece is (1)/(9) yard long.
We can represent this as an equation:
(2)/(3) ÷ (1)/(9) = ?
To divide fractions, we multiply by the reciprocal of the second fraction:
(2)/(3) x (9)/(1) = ?
Multiplying across, we get:
(2 x 9)/(3 x 1) = 18/3 = 6 pieces
