Can someone explain to me what I'm doing wrong? 68mL was wrong as well. Selecting "tenths place" for 3a and "hundredths place" for 3b and then putting a decimal was wrong as well. I'm lost as to what I should do.

Tens place

Ones place

69.5 ml

Explanation:

Hi! Sorry about your frustration.

Looking at the attachment again, I can then say that

3a) the answer would be only tens place. You may think ones place is correct, but then again look at the beaker. Are there any measurement in ones graduated on it? The question says "certain", while it's possible to calculate in ones, you most likely would be guessing and not certain about it.

3b) from the explanation I did in 3a above, it is thus clear ones place is the answer here. Calculating in tens is very certain, calculating in tenth and hundredth place is quite hard, if not impossible. Therefore, ones place is possible, but uncertain.

3c) If both 68 & 69 are incorrect, I'd advise you try something even much closer to 70, in 69.5

Kindly vote brainliest, thanks
