Write the ratio as a fraction in simplest form, with whole numbers in the numerator and denominator. 40 l : 64 l how do you work this out?

40 as the numerator and 64 as the denominator which can be simplified to 5 over 8

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
