Mrs burkens grandma bought a strip of fabric 10yd long she needs 1 1/3 yard piece to make each pillow how many pillows can she make
Like I don’t know I’ve been trying for 1 hour
10/(1 1/3) = 10 / 4/3 = 10 * 3/4 = 7 1/2
so, 7 pillows
To calculate how many pillows Mrs. Burken's grandma can make, we can divide the total length of the fabric by the length needed for each pillow.
First, let's convert the mixed number 1 1/3 into an improper fraction:
1 1/3 = (3*1 + 1)/3 = 4/3
Next, we can find out how many 1 1/3 yard pieces can fit in a 10-yard strip of fabric by dividing the total length by the length needed for each pillow:
10 yards ÷ (4/3) yards/pillow
To divide fractions, we multiply the dividend (10) by the reciprocal of the divisor (4/3):
10 yards × (3/4) yards/pillow
Now we can simplify the equation by canceling out the common factors between the numbers:
(10 × 3) yards / (4 × 1) yards/pillow
= 30 yards / 4 yards/pillow
Simplifying the units, we get:
= 30/4 pillows
= 7 2/4 pillows
To express the answer in a mixed number, we divide 30 by 4 and write the remainder as a fraction:
7 2/4 = 7 1/2
Therefore, Mrs. Burken's grandma can make 7 and 1/2 pillows with the 10-yard fabric strip.
