Answer: 98! :)
Explanation:
4/3 = ?/42
42 divided by 3 is 14.
Multiply 14 x 4 = 56.
4/3 = 56/42
Now you add 56 + 42 = 98.
So basically, 0.724 is being rounded,
when you are rounding, if the number next to it is less than 5, it stays the same if it is above 5 it increases 1. So we are rounding 7 correct? the number next to it is 2, and 2 is below 5. Therefore 0.724 rounded is 0.700
Since you asked how to solve this, I will put the answer at the bottom.
You might not think the same way as I but I think in steps.
<h3>(1) Calculate how many times the bacteria divide in eleven hours</h3>
The bacteria divide every 20 minutes, and will therefore divide three times every hour, 60/20 = 3.
If the bacteria grow for eleven hours, each bacterium will divide 3 times per hour × 11 hours = 33 times.
<h3>(2) Add the orginial size of bacteria into the equation</h3>
