Your question is not about algebra.
For a fraction in lowest terms, look for the largest common divisor. In this case, it is 8.
64/24 = 8*8/(3*8) = 8/3
If it is a fraction and in lowest terms, that is the only way to write it. The other would be as a mixed number: 2 2/3
write the ratio as a fraction in simplest form in two ways for 64/24
