Question

a biologist is looking for a rare flower in a park forest. Which ratio represents less that 1% of the whole?

A: 1 flower out of 50 flowers
B: 2 flowers out of 180 flowers
C: 1 flower out of 150 flowers
D: 5 flowers out of 500 flowers

Answer 1

c

Answer 2

If you can reduce the fraction to something like 1/100 and the denominator is greater than 100, then the percent will be less than 1

Answer 3

1% means 1 out of a 100.
A. 1 out of 50 is clearly more than 1 out of 100
B. 2 out of 180 is the same as 1 out of 90, which again is more than 1 out of 100
C. 1 out of 150 is clearly more rare than 1 out of 100
D. 5 out of 500 is the same as 1 out of 100

so, as @hero indicated, option C is the rarest flower.

Answer 4
