What is 5/10 + 8/100

Greeley [361]

Answer:

$\frac{29}{50}$

Step-by-step explanation:

We have two fractions and are being asked to add them both.

5/10 and 8/100 don't have the fractions, but 5/10 can be simplified to 1/2, meaning that to make the same denominator, we have to find the half of 100, which would be 50. Now turn the fraction into 50/100.

50/100 + 8/100

58/100

This can be simplifed :

$\frac{58/2}{100/2}$

$\frac{29}{50}$
