Mrs brown baked a blueberry pie she gave 1/5 of the pie to her sister and another 1/5 to her neighbor. what percentage of the blueberry pie was left

If Mrs. Brown gave away 1/5 of the pie to her sister and another 1/5 to her neighbor, she gave away a total of 1/5 + 1/5 = 2/5 of the pie.

The remaining percentage of the pie is 1 - 2/5 = 3/5.
To convert this fraction to a percentage, you divide the numerator (3) by the denominator (5) and multiply by 100: (3/5) x 100 = 60%
Therefore, 60% of the blueberry pie was left.
