Question

Nan says 21/4 is equal to 5 1/4. Dorothy says it is equal to 4 1/5. Who is correct? Show your work to prove the right answer.

Answer 1

Answer: Nan

Explanation:

21 divided by 4 is 5.25

if you turn that into a fraction, it will be 5 1/4.

if a decimal ends in .25 it will be equivalent to the fraction 1/4

think of it like with quarters, four of them make 1.00 and on quarter makes .25

Answer 2

21/4 is equal to 5 1/4

Explanation:

converting improper fraction to mixed fraction

21/4 = (4*5 + 1 )/ 4 = 5 1/4

and 4 1/5 = (4*5 + 1) / 5 = 21 / 5

so Nan is correct
