A scientist is growing bacteria in a beaker. At this rate, in 4 hours, 122 bacteria have grown. How many bacteria will grow in 6 hours?

1 answer

To find the number of bacteria that will grow in 6 hours, you can create a proportion:

4 hours / 122 bacteria = 6 hours / x bacteria

Cross multiply to solve for x:

4 hours * x bacteria = 6 hours * 122 bacteria

4x = 6 * 122

4x = 732

Divide both sides by 4 to solve for x:

x = 732 / 4

x = 183

Therefore, in 6 hours, 183 bacteria will grow.
