The number of microorganisms that I will have after 10 days would be: 245.41 microoganisms.
<h3>How to calculate the number of microorganisms that I will have after 10 days?</h3>
To calculate the number of microorganisms that I will have after 10 days, I must perform the following operations:
We need to find 37% of 55 as shown below:
- 55 ÷ 100 = 0.55
- 0.55 x 37% = 20.35
- 55 + 20.35 = 75.35
So after 2 days I will have 75.35 microorganisms.
- 75.35 ÷ 100 = 0.75
- 0.7535 x 37% = 27.87
- 75.35 + 27.87 = 103.22
On the fourth day I will have: 103.22 microorganisms.
- 103.22 ÷ 100 = 1.0322
- 1.0322 x 37% = 38.19
- 103.22 + 38.19 = 141.41
On the sixth day I will have 141.41 microorganisms.
- 141.41 ÷ 100 = 1.4141
- 1.4141 x 37% = 52.32
- 141.41 + 52.32 = 193,73
On the eighth day I will have 193.73 microorganisms.
- 193.73 ÷ 100 = 1.9373
- 1.9373 x 37% = 71.68
- 193.73 + 71.68 = 265.41
On the tenth day I will have 245.41 microoganisms.

Jade hiked 1 1/4 miles on the trail. Gretta hiked 1 1/2 times as far on the trail as Jade.
Jade hiked = 
Gretta hiked = ![[tex]1\frac{1}{2} becomes \frac{3}{2}](https://tex.z-dn.net/?f=%5Btex%5D1%5Cfrac%7B1%7D%7B2%7D%20becomes%20%5Cfrac%7B3%7D%7B2%7D)
[/tex] times Jade hiked
So Gretta hiked = 
To multiply two fractions, we multiply numerator with numerator and denominator with denominator
Gretta hiked = 
miles
