Carrie has a 10ft long plank of wood. She want's to cut three pieces that are each 2 2/3 feet long from the plank. how long will the plank be after she cuts off the three pieces?
10 - (2 * 2 2/3) = ?
I think it should be 10 - (3* 2 2/3), since Carrie wants to cut three pieces of wood. which should give you the answer of 2 ft of wood left.
10- (3* 2 2/3)=
10- (3* 8/3)=
10-8= 2ft
Oops -- Gaby is right. I goofed!
2 ft of wood left.
To find out how long the plank will be after cutting off three pieces, we first need to calculate the combined length of the three pieces being cut.
Each piece is 2 2/3 feet long, which is the same as 8/3 feet. To find the combined length, we multiply this by 3 (as there are three pieces being cut):
8/3 feet × 3 = 24/3 feet
To simplify the fraction, we divide both the numerator and denominator by 3:
24/3 feet ÷ 3 = 8/1 feet = 8 feet
So, the combined length of the three pieces being cut is 8 feet.
Now, to find out how long the plank will be after cutting off the three pieces, we subtract the combined length from the initial length of the plank.
Initial length of the plank = 10 feet
Combined length of the three pieces = 8 feet
To find the remaining length of the plank, subtract the combined length from the initial length:
10 feet - 8 feet = 2 feet
Therefore, the plank will be 2 feet long after cutting off the three pieces.
