Part B: Fill in the Blank
Write the correct answer on each line.
1. From 4/8, 6/12, and 4/12, the fraction NOT equivalent to 1/2 is 4/12.
4/12 simplifies to 1/3, not 1/2, while 4/8 and 6/12 both simplify to 1/2.
2. Lola ate 6/8 of a chocolate bar. In simplest form she ate 3/4 of the bar.
Dividing numerator 6 and denominator 8 by 2 gives 3/4, the simplest form of 6/8.
3. Five friends fairly shared a pizza. Each got 2/10. In simplest form each got 1/5.
Dividing top and bottom of 2/10 by 2 gives 1/5, so each friend got one fifth.
4. From 8/12, 4/6, and 1/3, the fraction NOT equivalent to 2/3 is 1/3.
1/3 is not equivalent to 2/3, while 8/12 and 4/6 both simplify to 2/3.
5. On a number line, 6/10 lands at the same point as 3/5.
6/10 simplifies to 3/5, so they share the exact same point on a number line.
