How many pieces of carpet can be cut from the roll if each piece is to be 2/5 meter long?
depends on the length of the roll, which you did not state
Whatever it is, divide it by 2/5 m
e.g. suppose it is 30 m long
number of pieces
= 30/(2/5)
= 30(5/2)
= 75 pieces
A roll of carpet is three meter long. How many pieces of carpet can be cut into the role if each piece is to be 3/4 meter long ?
To find out how many pieces of carpet can be cut from a roll, first, we need to know the length of the roll. Once we have that information, we can divide the length of the roll by the length of each piece to determine the number of pieces that can be cut.
Let's assume the length of the roll is L meters.
To calculate the number of pieces of carpet that can be cut, we need to divide the length of the roll by the desired length of each piece:
Number of pieces = L / (2/5)
To divide by a fraction, we multiply by its reciprocal:
Number of pieces = L * (5/2)
This can be simplified by canceling out common factors:
Number of pieces = (L * 5) / 2
So, the number of pieces of carpet that can be cut from the roll is (L * 5) / 2.
