Question

Why is 7.4 equal to 7.400?

Answer 1

Because they are both the same value and the decimal points on both numbers are on the same area. Since the two zeros at the end of the 2nd number mean nothing, it's the same exact number.

I tried to explain it as good as I can. Hope this helps.

Answer 2

Step-by-step explanation: These two decimals are equal to each other because the zeroes in 7.400 don't change it's value.

So, after a decimal point, zeroes don't change the value of the decimal.

So we can simply drop the zeroes to see that 7.4 = 7.4.
