What is one divided by one tenth?

Answer 1

10

Edit: I almost "improved" this answer to be: 0.10

then I looked at it harder and realized the original answer was correct.

One TIMES one tenth would be 0.10, but one DIVIDED by one tenth would be 10.

(my bad)

The rule for dividing by fractions is to cross-multiply.

So one is turned into a fraction by making it 1/1

and one-tenth is the fraction 1/10.

I'll cross multiply by turning the second fraction upside-down, and then multiplying straight across.

So 1/1 times 10/1 = 10/1, which is the same as 10.

Answer 2

1/10 divide by 1
