What is the best estimate for the following quotient? 891.3 divide 28

Well, 891.1 is close to 900 and 28 is close to 30, so 900/30 = 30, so that would be a good estimate! Hope this helped!

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.
