Explain why 0.7=0.70.
You can add zeroes after the last counting number and it doesn't change the value.
0.7 = 0.70 = 0.700 = 0.7.0000
To understand why 0.7 is equal to 0.70, it is important to first understand decimal numbers. In the decimal system, each digit in a number represents a different place value. The rightmost digit represents the "ones" place, the next digit to the left represents the "tenths" place, the following digit represents the "hundredths" place, and so on.
In the case of 0.7, the digit 7 is in the "tenths" place, meaning it represents 7/10 or 0.7. This can also be written as 0.70, where the zero is in the "hundredths" place, indicating that there are no hundredths in this number.
Since the zero has no effect on the value of the number, 0.7 and 0.70 are essentially the same. It is simply a different way of expressing the same value. The zero after the decimal point in 0.70 is added to indicate that there are no hundredths, but mathematically it does not change the value of the number.
