What is four tenths minus one fifth?

Answer 1

Well since we know that 4 and 10 can both be divided by two, the end result would be 2/5. Then we can determine that the common denominator of 2/5 and 1/5 is 5. Since you have a common denominator you can simply subtract the numerators. So the answer would be 1/5.

Answer 2

To subtract fractions, you need a common denominator. In this case, the least common denominator is 20. Four tenths is equivalent to eight twentieths, and one fifth is equivalent to four twentieths. Therefore, eight twentieths minus four twentieths equals four twentieths, which can be simplified to two fifths.
