What is the decimal multiplier to increase by 6.1%?

Given a: b and b: c, find a: b: c. write the ratio in simplest form. a: b=6: 10 and b: c=21: 33

Which of these numbers of simulations of an event would be most likely to produce results that are closest to those predicted by probability theory? 15, 20, 5, 10

15 and 14.7 are 1 apart, so 15 – 14.7 must be 1.
