Question

Mushrooms produce a tremendous number of spores. However, very few spores go on to establish a new mushroom colony. A "colony" is actually a little bunch of fuzzy-looking cells called a mycelium. Let's say a particular mushroom produces a billion spores in a day. If two-thirds of one percent of those spores successfully produces a new mycelium, how many of the spores were successful?

Answer 1

6,666,667

Explanation:

One billion is: 1,000,000,000

1% is 0.01

2/3 of 1% is 2/3 × 0.01

2/3 of 1 % of one billion is

2/3 × 0.01 × 1,000,000,000 =

= 6,666,667

Answer 2

6,666,667

Explanation:

One billion is: 1,000,000,000

1% is 0.01

2/3 of 1% is 2/3 × 0.01

2/3 of 1 % of one billion is

2/3 × 0.01 × 1,000,000,000 =

= 6,666,667
