To calculate a percentage, you generally divide the part by the whole and then multiply by 100. For example, to find what percentage 20 is of 50, you would divide 20 by 50 to get 0.4, and then multiply by 100 to get 40%. So, you divide first and then multiply to express it as a percentage.
To divide 8 into tenths, you would multiply 8 by 1/10. This gives you 0.8, which is the equivalent of one-tenth of 8. So, you multiply rather than divide in this case.
