|
When dividing a whole number by a power of 10, the decimal point in the quotient is shifted to the right the same number of places as the exponent of 10
Divide 7,786 by 100, and count the number of zeros in 100, we can see there are two zeros. So we put the decimal point two places to the left, i.e 7,786 ÷ 100 =77.86.
