Ineed i do not understand i'm only 8

1) 8

2) 42

3) 4

4) 17

5) 6

7) 60

Step-by-step explanation:

1. Yes, because 1 minus 3 can't happen, since 3 is bigger than 1.

2. No, because 6 minus 4 can happen, since 6 is bigger than 4.

3. No, because 9 minus 5 can happen, since 9 is bigger than 5.

4. Yes, because 5 minus 8 can't happen, since 8 is bigger than 5.

5. Yes, because 0 is nothing, and you can't subtract a number bigger than it by it.

6. No, because a number can be subtracted by itself to get 0.

Step-by-step explanation:

When you subtract 2 numbers, you have to sometimes carry a number over to the first digit (meaning put the number that you had over the first digit of the first number). Here is an example:

5 67 17

-29

36

You have to subtract, and since 7 is smaller than 9, you have to borrow 10 from the 6 in 67, so that you add 10 to 7, to make 17, which is bigger than 9 and can be subtracted. When you do that, you get 6, so you put the 6 down, and cross out 6 to make it 5, since it is in the 10ths place, it makes sense to change it to 5. Subtarct the numbers, and you get your answer!

I hope this helps :)

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

i think asking google will you get the answer to that question
