Some college roommates want to make pancakes for their neighbors. They need 55 cups of flour, but have only a one third
1
3-cup measuring cup. How many times will they need to fill their measuring cup?
Express using positive exponents and simplify, if possible.
−8−1 + 8−2
To find out how many times they need to fill their one-third cup measuring cup, you can divide the total amount of flour needed (55 cups) by the size of their measuring cup (one-third cup).
Let's calculate:
55 cups ÷ (1/3 cup) = 55 cups × (3/1) = 55 cups × 3 = 165 times
Therefore, they will need to fill their one-third cup measuring cup 165 times.
To find out how many times they will need to fill their one third (1/3) cup measuring cup to get 55 cups of flour, we can use division.
Divide the total amount of flour needed (55 cups) by the amount that can be measured with each cup (1/3 cup).
55 ÷ 1/3
To divide by a fraction, we can invert and multiply. So, we need to multiply 55 by the reciprocal of 1/3.
55 × 3/1
Multiplying 55 by 3 gives us:
165/1
Which simplifies to:
165
Therefore, the college roommates will need to fill their measuring cup 165 times.
55/(1/3)
55 * (3/1) = ?
