Question

Is 18% larger than 0.7

Answer 1

No. 18% in decimal form is 0.18. 0.7 (or 0.70) is more than 0.18. In other words, 
18% < 0.7

Answer 2

No because if you were to make .7 a percent it would be 70% because it is 1 number and no extra zero before 7 so it is below 100 so 18 percent would be .18 so 18% is larger.
