Answer:
To find the sum of 3/10 and 4/100, we need to first find a common denominator. In this case, the least common denominator is 100:
3/10 + 4/100
To make the denominators the same, we can rewrite 3/10 as 30/100:
30/100 + 4/100
Now, we can add the fractions:
30/100 + 4/100 = (30 + 4)/100 = 34/100
So, the sum of 3/10 and 4/100 is 34/100.
