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
One fourth is five twentieths. Nine twentieths minus five twentieths is four twentieths. Four twentieths is one fifth.
nine twentieths
Nine twentieths, or just under one half.
There are 100 cents in one dollar. Therefore, nine twentieths of a dollar is equal to 9/20 x 100 = 45 cents.
thirty-one and nine twentieths
nine fourths or 9/4 is equal to 2.25
5 and nine twentieths is the same as 109/20 = 5.45
nine twentieths in percentage = 45%= 9/20 * 100% = 0.45 * 100% = 45%
45 / 240 = 9 / 48 = 3 / 16
It is 0.95
No - expressed as a fraction in its simplest form, -0.45 is equal to -9/20 or minus nine twentieths.
If the whole number is twelve, three fourths? No, nine tenths of twelve would not be a complete fraction. Eighteen twentieths would equal nine tenths, or 90 percent if you're looking for a metric answer.
