Complete the statements below to answer the question.

Answer 1

Answer: no

Step-by-step explanation: to change a fraction back to a improper fraction

multiply the whole number by the denominator and then add it to the numerator but be careful with negative.  You can check this process by changing the improper fraction back to proper. If i change -17/10 i get -1 7/10.  the correct answer is -23/10.
