Everett is reading a book for his language arts class. He read 1/3 of the book on Saturday, 3/8 of the book on Sunday and 1/4 of the book on Monday. Which procedure can Everett use to find the total fraction of the book he has read?
A.Write the equivalent fractions using a common denominator then subtract the fractions from 1
B.Write equivalent fractions using a common denominator then find the sum of the fractions
C.Find the sum of 1/3 and 3/8 then subtract 1/4
D. Add the numerators of all 3 fractions then add the denominators
B?
Right.
Robert is cutting wooden strips from a foot long piece of wood for his woodworking class. He needs a strip of wood that is 3/8 foot long and another strip that is 1/2 foot long. Which of the following strips is shaded to show the total amount of wood Robert needs for his class?
A.5/8
B.3/8
C.2/8
D.7/8
D?
Amanda made 3 hair bows using 2/3 yard ribbon each. She made 2 bows using 1/2 yard each. Which shows the amount of ribbon Amanda used to make the bows?
A.(2/3+2/3+2/3)+(1/2+1/2)
B.(2/3+2/3)+(1/2+1/2)
C.2/3+1/2
D.2/3-1/2
A?
Both are right! :-)
Thank you
You're welcome.
To find the total fraction of the book Everett has read, he needs to combine the fractions representing the portions he read on each day.
Let's break down the options to determine which procedure can be used:
A. Write the equivalent fractions using a common denominator then subtract the fractions from 1:
This procedure would work if we wanted to find the fraction of the book that Everett has not read. Since we want to find the fraction he has read, this option is not appropriate.
B. Write equivalent fractions using a common denominator then find the sum of the fractions:
This procedure is correct because Everett needs to find the total fraction of the book he has read. By writing equivalent fractions using a common denominator, he can combine the fractions representing each day's reading and find their sum.
C. Find the sum of 1/3 and 3/8 then subtract 1/4:
This procedure would only give the fraction of the book that Everett has read on two specific days (Saturday and Sunday) and subtracts the fraction he read on Monday. It does not account for the total fraction he has read, so this option is not appropriate.
D. Add the numerators of all 3 fractions then add the denominators:
This procedure does not provide an accurate result. Adding just the numerators and denominators would give the incorrect total fraction without considering the relationships between the parts and the whole.
So, the correct answer is B. Everett should write equivalent fractions using a common denominator and then find the sum of the fractions to determine the total fraction of the book he has read.
