So to find how many tenths, or 1/10's, there are in four fifths, or 4/5, divide 4/5 by 1/10.


(4)/(5) / (1)/(10)

Now, remember that dividing by a number is equivalent to multiplying by its reciprocal. To find the reciprocal, just flip the numerator and denominator around. In this case, 1/10 would become 10/1. Flip 1/10 to its reciprocal, change the sign to multiplication, and multiply numerators with numerators and denominators with denominators:


(4)/(5)* (10)/(1)=(40)/(5)=8

In short, there are 8 tenths in four fifths.
