Mary had a piece of pie. She gave 1/3 to her mother. What fraction of the pie is left with her?
1 - 1/3 = 3/3 - 1/3 = 2/3
To find out what fraction of the pie is left with Mary, we need to subtract the fraction she gave to her mother (1/3) from the total fraction of the pie.
The total fraction represents the whole pie, which is 1. So, to find out the fraction left with Mary, we subtract 1/3 from 1.
To subtract fractions, we need a common denominator. In this case, the denominators are already the same (3), so we can subtract the numerators directly.
1 - 1/3 = 3/3 - 1/3 = 2/3
Therefore, Mary has 2/3 of the pie left.
To find out what fraction of the pie is left with Mary, we need to subtract the fraction she gave to her mother from the whole pie.
Since Mary gave 1/3 of the pie to her mother, it means she has 2/3 of the pie remaining.
So, 2/3 of the pie is left with Mary.
