6 is 3 percent of the number 200.
To find the number that 6 is 3% of, we can use the concept of percent as a ratio.
Let's represent the unknown number as "x".
We can set up the equation:
3% of x = 6
To solve for x, we need to divide both sides of the equation by 3% (which is equivalent to dividing by 0.03):
(3% of x) / 0.03 = 6 / 0.03
Simplifying further:
x / 0.03 = 200
To isolate x, we can multiply both sides of the equation by 0.03:
x = 0.03 * 200
x = 6
Therefore, 6 is 3% of the number 200.

a. Okay, so you multiply the 4.7 and 2.9 together, and then add the exponents
13.63 * 10^10
But we are not done. There can only be one digit in front of the decimal point. So, you move the 13.63 back one place so 1.363. But we have to do this to both sides, so the answer is 1.363 * 10^11.
b. Now you divide the 5.8 and 2, and subtract the exponents.
2.9 * 10^-5
The negative exponent is fine in this case if you were wondering.
c. Expand the scientific notation to 1500, then add the 2491 and then put that in scientific notation is what I would do. You can also express 2491 in scientific notation and add them. Either way you will get 3.991 * 10^3
d. Same thing here except with subtraction. The answer is 6.5 * 10^-4.
This was a little long, sorry. Let me know if you need further explanation. I hope this helps.
