125 5 of 20 is 1 of every 4. 1 of every 4 is 25 out of 100, which is 25 percent.
270 Stars are 40 and moons are 30, so 70 stickers out of 100 are not hearts. That is 70 percent.

41-D, 2-C, 3-B, 4-A 10% is one tenth: 9. 25% is one fourth: 10. 20% is one fifth: 12. 50% is one half: 35.
5360 45 percent is 40 percent and 5 percent: 4 × 80 + 40 = 360.
612 10 percent of 80 is 8 and 5 percent is 4. 8 + 4 = 12 dollars.
