Explain how to determine where to place the decimal point in the answer when multiplying two decimals.

The solution to the question 58 days and the decimal equivalent of rational number, Some sequences of digits will start reporting itself, So to show that is mill equivalent of fraction 124 x 9 90 indicated a rational number. Using calculator. We found out that this will be colon 20.125 to 5 to 5 to 5 to 5 3. Now observed that the 25 repeats itself after the decimal places up to seven times. So that's the decimal equivalent of the given fraction is indicated as 0.125252 5-5-5 3. We see that the last digit is three. This is different because it is the rounding NAFTA result. Thank you.

So this problem, We're going to explain why we line up the decimal points and corresponding place value columns when adding decimals. So I wrote out a little example for you of 10.6 plus 5.7. But we did not. I didn't line up the decimal points intentionally. This completely looks wrong, right? Because when you have 5.7, if we stripped away the decimal places and the decimals afterwards we would be left with this, and then it would just be temples. Five. And when we add 10 plus five together, we don't add the one in the five together. First, we add the zero in the five because those are both in the ones place, and the same goes for when we're using decimals. So let me write this in proper form 10.6 plus 5.7. Every place in each number has a specific name. So for 5.7, here's the ones. Please. This is the tens, and this is the 10th. If we wanted to add the tents together, we would not line it up like this because then we're adding the ones and the tents. We just have to make sure that we're always adding the specific places together. And the decimal place is a great way to figure out where you are because everything left in the decimal is ones tens, hundreds, so on. Everything to the right is tense hundreds, thousands. So that is why we always line up our numbers when we're adding decimals.

This time like it was 5/6, divided by 3/4 times in half. This division is the same thing as multiplying. It's reciprocal on. Let's see, from this 1/2 denominator, the two will go into the four on the top. Uh, nothing else. Councils don't know this to actually goes in a factor of two in the 63. Oh, ended with 5/9 more. Let's see what we get Somewhere around, uh, it blended with a zero plane. I am fine and they want three decimal places and round so 56 and this is empty.

Eso likeness into a calculator. This is approximately a 3.68

Energetics of Symport Suppose that you determined experimentally that a cellular transport system for glucose, driven by symport of $\mathrm{Na}^{+},$ could accumulate glucose to concentrations 25 times greater than in the external medium, while the external $\left[\mathrm{Na}^{+}\right]$ was only 10 times greater than the intracellular $\left[\mathrm{Na}^{+}\right] .$ Would this violate the laws of thermodynamics? If not, how could you explain this observation?
