What is 0.009% of 5000? Round to the nearest hundredth (if necessary).

0.045

Step-by-step explanation:

If you recall, I answered a similar question of yours recently. I told you that you just multiply the percent in decimal form by 5000.

0.0009% is the same as 0.000009.

0.000009 x 5000 = 0.045

0.45  that's forty-five hundredths. No further rounding required.

Step-by-step explanation:  To convert the percent to decimal, shift the decimal point two places to the left. .009%  becomes .00009  Then multiply that by (of means multiply when you convert word problems to equations) 5000.

.00009 × 5000 = .45  Quick on a calculator.

Old Style: 9 x 5000 = 45000. but since the 9 is in the 5th decimal place, you move the decimal 5 places to the left and end up with .45000 but you can drop the useless zeros to the right and put a zero to the left of the decimal for clarification-- in case someone doesn't notice the decimal point.  0.45
