7⁷ → 4. Our pattern here is 0, 4, 4, 0. Once again, we can see this as a block of 4. Dividing the exponent by 4 and having a remainder of 1 or 0 means the tens digit will be 0. Dividing the exponent by 4 and having a remainder of 2 or 3 means the tens digit will be 4. 1993 divided by 4 yields a remainder of 1.

So just like we can reduce fractions, we can also reduce ratios. So if you divide 6 and 9 both by 3. 6 divided by 3 is 2. 6 divided by 3 is 2. And 9 divided by 3 is 3. So we could also say that the ratio of apples to oranges is 2 to 3. Or if we want to use this notation, 2 to 3. 2 to 3.
