Why is 0.07 and 0.70 equivalent?

Answer 2

0.07 and 0.70 are equivalent because the value of each digit in a decimal depends on its position. In 0.07, the 7 is in the hundredths place, while in 0.70, the 7 is in the tenths place. Since there are no other digits after the decimal point, both numbers represent the same value: 7/100.
