Question

What is 1 4 add 2 5 in frations

Answer 1

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.
