Add. $$.0 .43+0.8+0.561$$
So let's multiply the three by the eight, which is 24 4 Carry the two three times seven is 21 plus it to his 23 3 and carry the two and three times zero is zero plus to To is to put a zero placeholder. And now let's do the 22 times 8 to 16 carry the one to 10 7 14 Plus that one is 15 5 carry the one in two time 00 plus the one is one now. This adds A four plus year was four. Three plus six is nine two plus 5 to 7, and then the one. The death will lose once and twice in the first number and then once on the second number, the street total. So Lou the decimal and 123 times from the floor there. So 1.794
Add these decimals. I'm gonna place this vertical and line up my decimal points. Like so. So when I add these up, six is the only thing in this common vie plus two plus one in this column. That's eight. There's my decimal point right there in eight plus 3 11 11.86 is the sum of these three decimals.
Right. So this problem were asset to positive integers. Those integers are 48 in 90. So once we have the ones column in the tens, calm lined up, we can go ahead and add. So eight post zero is just going to be eight, and then four plus nine is going to be 13 so our answer is going to be 138.
We want to do problem number 11. This question we have toe Just's obstruct. 90 degree manners, 34 degree, 12 minute, 34 degree terminate. So let us just subscribe these two. If you subtract little just started like this, that 90 degree on it is obstructed toe. 34 degree on 12 minutes. I got 34 degree and tolerance. So what we can do? We can write this 90 degree we compared to this 90 degree as 89 degree and 60 minutes. Okay, Now let us absurd this. So 10 plush 10 managed to turn. Managed to is 86 minutes. One this terminus to his at night becomes five five minutes. When is four? So 48 minutes now. Here. 19 minutes for this is five on eight. Ministry. This is five. So we got 55 degree and 48 a minute as the answer to five degrees on 48 minutes. The answer. Thank you.
