Question

What number is 1/ 10 of 8,000,000?​

Answer 1

when multiplying by 10 we add a 0 at the right side of the number (we move the decimal point one position further to the right).

when dividing by 10 we cut a 0 off the right side of the number (we move the decimal point one position further to the left).

so,

8,000,000 / 10 = 800,000
