What is 1 4 add 2 5 in frations
fgiga [73]

Answer:

\frac{1}{4} +\frac{2}{5}= \frac{13}{20}

Decimal form: 0.65

Step-by-step explanation:

\frac{1}{4} +\frac{2}{5}

To add, you need to get the denominators to be the same, so find the lowest number that both 4 and 5 fit into (multiplication):

4, 8, 12, 16, 20

5, 10, 15, 20

20 is the lowest common multiple of both. So multiply \frac{1}{4}  by 5 (both top and bottom) and \frac{2}{5}  by 4 (top and bottom) so that the denominators will have the same value:

\frac{1(5)}{4(5)}+ \frac{2(4)}{5(4)}

Simplify

\frac{5}{20}+ \frac{8}{20}

Now you can add the numerators. Keep the denominators the same:

\frac{13}{20}

This is the most simplified version.
