When will dividing a whole number by a fraction result in a whole number answer? explain.

From these examples, we can conclude, we will get a whole number  when we divide if the numerator of the fraction  is a factor of the whole number

Step-by-step explanation:

Lets look at a couple of examples

Example 1

4 ÷ 1/3

Copy dot flip

4 * 3/1 = 12

Whole number

Example 2

2 ÷11/12

Copy dot flip

2 * 12/11

24/11

11 goes into 24 2 times  

11*2 = 22  

24-22 =2

11 goes into 24  2 times with 2 left over,  The left over goes over the denominator.

2 2/11

2 2/11 is  a mixed number not a whole number

Example 3

8 ÷2/11

Copy dot flip

8 * 11/2

88/2

44

From these examples, we can conclude, we will get a whole number  when we divide if the numerator of the fraction  is a factor of the whole number

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
