What is the sum of4/10 and 40/100

40/100 = 4/10

4/10 + 4/10 = 8/10 = 4/5

To find the sum of 4/10 and 40/100, we need to first ensure that the fractions have a common denominator.

The denominators of 4/10 and 40/100 are already multiples of each other, as 10 is equal to 100/10. So, we can add the fractions:

4/10 + 40/100

Next, we need to make the denominators of both fractions the same. To do this, we can multiply the numerator and denominator of the first fraction (4/10) by 10, and the numerator and denominator of the second fraction (40/100) by 1:

(4/10)*(10/10) + (40/100)*(1/1)

Simplifying, we get:

40/100 + 40/100

Now that the fractions have a common denominator, we can simply add the numerators:

40 + 40 = 80

The sum of 4/10 and 40/100 is 80/100. However, to simplify the fraction, we notice that both the numerator and denominator can be divided by 20:

80/100 = (80/20)/(100/20) = 4/5

So, the simplified sum is 4/5.
