Simple math question..The Remainder?

Question

what is the remainder and how do i answer a question like what is the remainder of 30%4

thanks

Answer 1

In division, you find out how many times a number subtracts from a larger number. In your example, 4 subtracts from 30 seven times, since 4*7 = 28. After you have subtracted it 7 times, your 30 has been reduced to 2, which is the remainder.

If you want to use a calculator, do it like this:
30 / 4 =
7.5
Now, use the 7 and ignore the .5, and enter:
4 * 7 =
28
Subtract that from 30:
30 - 28 =
2 <-- the remainder

Answer 2

30/4 asks how many times 4 fits into 30

4 fits into 30 7 times because 7 x 4 is 28

30
-28
= 2

4 won't fit into 2 at all so 2 is your remainder.

Answer 3

When talking about whole numbers, you can divide two numbers in a unique way of the form:

a = bq +r with 0 ≤ r < b

and r is called the remainder.

Ex: 30 = 4(7) +2
r = 2

50/7 can be written
50 = 7(7) +1

24/5:
24 = 5(4) +4

Note that in all these examples r is positive but always smaller than b

Answer 4

The remainder is what's left over. 4 doesn't divide evenly into 30.
30 divided by 4 would equal 7 ( 4x7=28) with a remainder of 2. The answer is usually written 7 R2. Good luck.

Answer 5

A remainder is the balance of a subtraction. If you are sub. 4 from 30 your remainder is 26.

Answer 6

With appreciate, i imagine you're difficult the perception of remainders with decimal notation. 10.3 does not mean that the the relax is 3. It skill "10 element 3", or 10 and three tenths. the actual answer is 10.33333... the position the 3s flow on for ever ("10 element 3 worry-free"). In the relax words, it really is 10 the relax 2 (this isn't a similar as 10.2). This does upload up (10x6+2=sixty 2). because you divided via 6, the the relax is two/6 ("2 sixths"). That simplifies to at least a million/3 ("one 0.33"). i'm hoping this helps.
