A contractor cut 28 feet of wire into sections that were 4 2/3 feet long. How many pieces of wire did the contractor have?
Answers
Answer:
4 2/3=14/3
Step-by-step explanation:
divide 28 by 14/3 and get no. of pieces=28*3/14=6 pieces

Answer:
To find the no. of pieces, we have to divide the total length of the wire by the length of each piece, which is 28 ÷ 4 2/3
As we cannot divide by a mixed number, we change it to an improper fraction.
4 2/3 becomes 14/3.
To divide by a fraction, we invert the divisor( explaination below) and change the divide operation to the multiplication operation.
Hence, 28 ÷ 14/3= 28 x 3/14.
We can then simplify it by cross cancellation(explanation below).
28 x 3/14 = 2 x 3 = 6
Ans: He has 6 pieces of wire.
Divisor: The no. being divided by.
Cross Cancellation: Dividing the numerator of a fraction or a whole no. and a denominator of another fraction by a number.
