A piece of string is 3 yards long. How many 1 1/4-yard long pieces can Julie cut from the string?
A. 1
B. 2
C. 3
D. 4
1 1/4 = 1.25
3-1.25=1.75
1.75-1.25=0.25
you can only cut two 1 1/4 yards from a 3 yards string.
Dude, it's B.
Ya it is B
So what's the answer?!
The answer is B, or 2.
2 strings can be cut from the 3 yard string.
To find out how many 1 1/4-yard long pieces Julie can cut from a string that is 3 yards long, we can divide the total length of the string by the length of each piece.
The length of the string is 3 yards. To find out how many 1 1/4-yard pieces can be cut, we divide 3 by 1 1/4.
To divide fractions, we need to convert the mixed number, 1 1/4, into an improper fraction.
1 1/4 is the same as (4*1 + 1)/4 = 5/4.
Now, we can divide 3 by 5/4.
Dividing a number by a fraction is the same as multiplying that number by the reciprocal of the fraction. So let's rewrite the problem as multiplication:
3 ÷ (5/4) = 3 * (4/5).
Multiplying 3 by 4/5 gives us (3 * 4)/(1 * 5) = 12/5.
Therefore, Julie can cut 12/5 yard long pieces from the 3-yard string.
To simplify this fraction, we divide the numerator and denominator by their greatest common divisor, which is 1.
12/5 ÷ 1 = 12/5.
So Julie can cut 12/5 yard long pieces from the 3-yard string.
Now, let's convert it back to a mixed number:
12/5 = 2 2/5.
So, Julie can cut 2 2/5 pieces from a string that is 3 yards long.
Answer: B. 2
