one twentieth 1 / 5 x 1 / 4 = (1 x 1) / (5 x 4) = 1 /20
That depends on what you mean: twenty add one fifth is 20 + 1/5 = 20 1/5 twenty, add one fifth (of twenty) is 20 + 1/5 * 20 = 20 + 4 = 24
4/5 + 2/20 = 4/5 + 1/10 lowest common denominator is 10 8/10 + 1/10 = 9/10
1/5 + 1/4 = 4/20 + 5/20 = 9/20
5 and 4/5 if you add them.
4 1/5 + 3 4/5 = 8
It is four fifths.
if your asking 8 subtracted by 6 and 4 fifth's. then the answer is 1 and 1 fifth
To do this calculation by hand, we can write: (1/20) * 4 = 4/20 = 1/5 = 0.2. We can also note that one twentieth is equivalent to 0.05. So, 4 * 0.05 = 0.2.
1 and 3 fifth
1/4 + 1/5 = 9/20 Answer: To add fractions with different denominators, get the Least Common Denominator (LCD) of the addends first, then add the numerators of the fractions. In 1/4 + 1/5, the LCD is 20. 1/4 = 5/20 1/5 = 4/20 .......===== ....... 9/20
It is: 4 and 1/5 = 4.2
