00:01
Okay, for number one, that's for the total mass of the cake and muffin.
00:06
We just have to add the mass of the cake in the mass of the muffin, such as this.
00:21
So 5 plus 0 is 5, 5 plus 2 is 7, 6 plus 5 is 11, so 1 plus is 4 plus 3 is 7, and plus 0 is 1 .7 ,000, so you are correct.
00:37
Next for number two, anna had 10 .589 liter of juice.
00:42
After peeling up to six identical battery juice, he had 3 .0 899 left of choose.
00:49
Find the amount of choose in each battle.
00:53
So first, let's determine the total amount of juice that goes to that six identical battles.
01:00
We have to minus 10 .5899 with the amount of juice that is left.
01:13
So, so it is 9 minus 90, 9 minus 0, 8 minus 8 is 0, 5 minus 0, 10 minus 0 is 5, 10 minus 3 is 7.
01:27
So we have 7 .5 liters.
01:31
Now, the 7 .5 liters, we have to divide it by 6.
01:45
Okay? so to divide 7 .5 by 6, first move the decimal point.
01:59
To the right.
02:06
So it becomes a fist.
02:15
Then in seven, we have one six, one times six is six, seven minus six, is one and then it's been down five.
02:26
Then in 15, we have two six, two and six is twelve.
02:33
15 minus 12 is three.
02:39
Then we can put a decimal point in here and here, put a second, then in 30 we have 5 6 5 .6 is 30 39 30 is 0 now we move the decimal back to here then the answer is 1 .25 liters so the direction is to write the letter the correct answer next number three we have a stringang salenko 4 .657 in a piece of note that has length of 2 566 what is the total length of two such string and the piece of float so you have to add the length of two strings and one piece of flow so this first two strings of plot so seven plus seven is 14 five plus five plus one is 11 seven plus six is 13 plus one is four plus three is seven four is eight then let's add the length of one piece of a clock 2 .5, 6, 6.
04:38
So, 4 plus 6 is 10, 1 plus 1 is 2, 3 is 5, 2, 2 plus 6 is 9, 7 plus 5 is 12, 2 plus 1 is 9, 10, 11, so the answer is 11 .29 5 meters...
