If Matt filled a 2 1/5 cup container, how many 1/5 cups

would he need to use??

2 1/5 = 11/5

2 1/5 = (2 * 5) + 1 = 11/5

To determine how many 1/5 cups Matt would need to fill a 2 1/5 cup container, we need to subtract the whole number, which is 2, from the total value, which is 2 1/5.

First, convert the mixed fraction, 2 1/5, into an improper fraction.

1/5 can be written as 1/5 * 5/5, which equals 5/25.
Adding 2 to the fraction gives us 2 + 5/25, which equals 10/25.

Now, simplify the fraction by dividing both the numerator and denominator by their greatest common factor, which is 5.

10/25 reduces to 2/5.

So, in total, Matt would need to use 2 1/5 cups, or 2 cups and 1/5 cups, which is equivalent to 2 1/5 cup or 2.2 cups.
