In order to find the number times something is larger than something, you have to use division where you divide the larger number by the smaller number.

So:

$\frac{3.19*10^8}{8.23*10^5} =387.6063183$

I'm not sure how much you want to round to, but the answer is 387.6063183 times.

You can make sure by multiplying the smaller number by 387.6063183 and you should get the larger number:

$8.25*10^5*387.6063183=3.19*10^8$

Rachel can make 3 bracelets in an hour. Oliver can make only 2 bracelets in an hour, but he already has 5 completed bracelets. C

Tanya [424]

Answer:

After 5 hours

Step-by-step explanation:

Given that Rachel can make 3 bracelets in an hour.

Let y be the no of bracelets and x no of hours.

Then equation for Rachael would be y = 3x ... i

Oliver is having initially 5 completed bracelets and every hour he would make 2 new bracelets

Hence equation would be

y = 2x+5 ... ii

Our question is why both will be equal

y would be equal in both if 3x=2x+5

Or x=5

After 5 hours form the start, both will have same number of bracelets.
