Part B: Fill in the Blank
Write the correct answer on each line.
1. From the list 2/4, 3/9, 5/10, the fraction NOT equivalent to 1/2 is 3/9.
3/9 simplifies to 1/3, not 1/2, while 2/4 and 5/10 both simplify to 1/2.
2. From the list 4/6, 2/3, 3/9, the fraction NOT equivalent to 2/3 is 3/9.
3/9 simplifies to 1/3, not 2/3, while 4/6 simplifies to 2/3 and 2/3 stays the same.
3. Sam ate 4/8 of a pie. In simplest form he ate 1/2 of the pie.
Dividing numerator 4 and denominator 8 by 4 gives 1/2, the simplest form of 4/8.
4. Two children fairly shared a chocolate bar. Each got 5/10. In simplest form each got 1/2.
Dividing top and bottom of 5/10 by 5 gives 1/2, so each child got half the bar.
5. From 6/9, 2/3, and 1/3, the fraction NOT equivalent to 2/3 is 1/3.
1/3 is not equivalent to 2/3, while 6/9 simplifies to 2/3 and 2/3 stays itself.
