5/10 plus 8/100 equals?

29/50

Step-by-step explanation:

To solve this expression, we first have to make sure that the denominators are equal. If the denominators aren't equal, we can't add the fractions together. To make equivalent denominators, the easiest way is to find the LCM. Looking at these two fractions, we see that the LCM is 100. To get to 100 from 10 in the first fractions denominator we multiply by 10. Since we multiplied by 10 in the denominator, we must multiply by 10 in the numerator, leaving us with the fraction:

5/10 = 50/100

Since the denominators are now equal, we can add these two fractions:

50/100 + 8/100 = 58/100 = 29/50
