Calculate one tenth of 930 pounds.

To find one tenth of an amount, we need to divide that amount by 10. And this is because there are 10 tenths in the total. So we have 930 pounds divided by 10. Now as the number that we’re dividing by 10 is an integer, that is, a whole number, with a last digit of zero, dividing by 10 will actually have the effect of just cancelling out this last zero. We’re left with 93 pounds over one, which is just equal to 93 pounds. So one tenth of 930 pounds is 93 pounds.

The other way to think about dividing by 10 is to think about place value. We currently have a nine in the hundreds column, a three in the tens column, and a zero in the units column. To divide a number by 10, we can keep the decimal point fixed but move all of the digits one place to the right. So the nine is now in the tens column, the three is now in the units column, and the zero is in the tenths column, giving 93.0. However, we don’t need to include the zero as 93.0 is the same as just 93. One tenth of 930 pounds is 93 pounds.
