Final answer:
To calculate the number of pieces made from a 2/5 meter long rod when each piece is 1/30 meter long, divide the length of the rod by the length of a piece. The calculation (2/5) ÷ (1/30) results in 12 pieces, hence 12 pieces can be made.
Step-by-step explanation:
The question involves calculating the number of pieces that can be made from a metal rod given its length and the length of each piece. Here, a metal rod is 2/5 meters long and will be cut into pieces that are each 1/30 meter long. To find out how many such pieces can be made, we divide the total length of the rod by the length of each piece.
- Divide the total length of the rod by the length of an individual piece: (2/5) ÷ (1/30).
- Cross multiply and simplify the fractions: 2 * 30 = 60 and 5 * 1 = 5, so 60 / 5 = 12.
- Thus, 12 pieces can be made from the rod.
