Number of the Day 17-25

The number of the day is 8675.309

17) Using the digits in the 1s and the 10s place respectively make a two digit number and write the prime factors.

Because of respectively make a two digit number you have to use the order that they said first which was the ones place, so the number in the 1s place is 5 then the 7 is in the 10s place. Now you make a number using that order so 57.

Because the prime factor itself is a prime number the only factors are 1 and itself.
So the prime factors are 57 and 1.

18) Add negative 2 to the digit in the 10s place using pictures.

-2+ 7=5

Diagram: There is two negatives - - and there is 7 postives + + + + + + +
So its asking to add them together. If your adding a negative number and a postive number what ever number in the equation is bigger thats the kind of number you'll get. Ex. -3+4.
4 is bigger than 3 so the symbol you'll have a postive. So now you have to make a zero pair. You have 2 negatives and 7 postives. You have enough +s so you put 2 negatives and postives together -+ -+ and you imaginaryly throw them away. Now you are left with +++++ and thats your answer.

19) Subtract negative 3 from the digit in the ones place using pictures

5-(-3)= +2

This is because you have five positives +++++ and 3 negatives - - - . Then you have to take away negatives, so you have enough postives so you make your zero pairs. So you end up taking away 3 zero pairs. +- +- +- and your are left with 2 positives + +. and thats you answer!!

20) Write a fraction using the 1000s place as the denominator and the tenths places as the numerator.

8675.309 in this number 8 is in the thousands place and 3 is in the tenths place.

If 8 is the denominator then its at the bottom blank/8 so now 4 is at the top 4/8 you can still simplify this into 1/2.

21) Use any 2 digits to make an improper fraction.

Just to remind you an improper fraction is a fraction where the numerator is bigger than the denominator.

So now you just choose 2 numbers where the numerator will be bigger than the denominator. Like: 8/5 , 7/6 and 9/3. You try and find the rest of the improper fractions.

22) Use any digits to make a mixed fraction.

A mixed fraction is a fraction where it has a whole number and a proper fraction.

Now just choose a number for a whole number, and number for a numerator and a number for the denominator. Make sure the numerator isnt bigger than the denominator or that will become a improper fraction. Like 3 4/8

23) Write the answer to the number 22 as a decimal.

3 4/8 So you first you know that you can simplify it so 4/8 is now 1/2. so its 3 1/2. Now you divide, so 1 divided by 2 then you'll get .5. Now you have the whole left so its 3.5

24) Draw a picture to represent the answer to number 22











Okay now you had 3 4/8 right? So there was 3 wholes, and 4/8 when i drew mine I did mine simplified into 1/2.
25) Write the answer is 21 as a percent.

Because there was alot of ways to make an improper fraction I will just pick one.

6/5 is my improper fraction. So now you just divide the numerator with the denominator. So its 6 divided by 5 is 1.2 then you multiply it by a hundred.

If This video doesn't work just go to this link to see the video !!!!!!! INTEGERS!!!
And If my post gets all spaced again it just does that by itself sometimes.

Here is a game to help you with adding and subtracting integers because I think that is the hardest thing to do in this whole thing. XD

HOPE THIS HELLPED!!
