How many 1 1/4 foot pieces can you cut from a piece of wood that is 20 ft long
or
20 / (5/4)
20 * (4/5) =
20 / 1.25 = ?
To find out how many 1 1/4 foot pieces can be cut from a 20-foot piece of wood, we need to divide the length of the wood by the length of each piece.
First, let's convert the length of each piece into a fraction. 1 1/4 can be written as 5/4.
Next, divide the length of the wood by the length of each piece:
20 ft ÷ (5/4) ft/piece
To divide by a fraction, we can multiply by the reciprocal:
20 ft × (4/5) ft/piece
Cancel out the common factor of 4:
20 ft × (1/5) ft/piece
Multiply:
20 ft × 1/5 = 20/5 ft
Simplify the fraction:
20/5 = 4
Therefore, you can cut 4 pieces of 1 1/4 foot length from a 20-foot piece of wood.
To determine the number of 1 1/4 foot pieces that can be cut from a 20-foot-long piece of wood, we need to divide the length of the wood by the length of each piece.
To calculate this, we can use the following steps:
1. Convert 1 1/4 feet into a decimal. To do this, we can rewrite it as 1.25 feet.
2. Divide the length of the wood (20 feet) by the length of each piece (1.25 feet).
20 feet ÷ 1.25 feet = 16
Therefore, you can cut 16 pieces of size 1 1/4 feet from a 20-foot-long piece of wood.
