To find two fifths, you take the number you want to find two fifths of and multiply it by 2/5. For example, if you want to find two fifths of 10, you would calculate (10 \times \frac{2}{5} = 4). Thus, two fifths of 10 is 4.
Four fifths.
To divide 4 by two-fifths, you can multiply 4 by the reciprocal of two-fifths. The reciprocal of two-fifths is five halves. Therefore, ( 4 \div \frac{2}{5} = 4 \times \frac{5}{2} = \frac{20}{2} = 10 ). Thus, 4 divided by two-fifths equals 10.
Two-fifths times one-fourth is two-twentieths or one-tenth, in simplified form.

To subtract two fifths from sixteen fifteenths, first convert two fifths to fifteenths. Two fifths is equivalent to six fifteenths (since (2 \times 3 = 6) and (5 \times 3 = 15)). Now, subtract: (16/15 - 6/15 = 10/15), which simplifies to (2/3). Therefore, sixteen fifteenths minus two fifths equals two thirds.
