Lynn is cutting a roll of cookie dough into slices that are 3/8 of an inch thick. The entire roll of cookie dough is 10 1/2 inches long. How many slices of cookie dough will Lynn get from the roll?
Delong
To find out how many slices of cookie dough Lynn will get from the roll, you need to divide the length of the roll by the thickness of each slice.
First, let's convert the mixed number 10 1/2 to an improper fraction.
10 1/2 = (10 * 2 + 1) / 2 = 21/2
Next, divide the length of the roll (21/2) by the thickness of each slice (3/8).
(21/2) ÷ (3/8)
Remember, when dividing fractions, you need to multiply the first fraction by the reciprocal of the second fraction.
(21/2) × (8/3)
To simplify, cancel out common factors.
(21/1) × (4/1) = 84/1
So, Lynn will get 84 slices of cookie dough from the roll.
To find out how many slices of cookie dough Lynn will get from the roll, we need to divide the length of the roll by the thickness of each slice.
First, let's convert the mixed number 10 1/2 to an improper fraction.
10 1/2 can be written as (10 * 2 + 1)/2 = 21/2
So, the length of the roll of cookie dough is 21/2 inches.
Next, we divide the length of the roll by the thickness of each slice.
21/2 ÷ 3/8
To divide fractions, we multiply the first fraction by the reciprocal of the second fraction.
21/2 * 8/3
Now let's simplify the multiplication.
(21 * 8)/(2 * 3)
168/6
The fraction 168/6 can be simplified further by dividing both the numerator and denominator by their greatest common divisor, which is 6.
168/6 = (168 ÷ 6) / (6 ÷ 6) = 28/1
So, Lynn will get 28 slices of cookie dough from the roll.
Therefore, the answer is 28.
(21/2) / (3/8)
(21/2) * (8/3) = _________
