What is 0.004% of 6800 round to the nearest hundredth

Elis [28]

Just remember that the word "of" means "multiply" in mathematical terms
Now lets get started working out this problem of yours
$0.004(6800) \\ \frac{0.004}{100} = 0.00004$ $0.00004(6800) \\ Actual Answer: 0.272 \\ Rounded Answer: 0.72$

Also, remember: $5$ and down is rounded to $0$ | $6$ and up is going closer to $10$
