Sara First you have to round the numerator and the denominator to the nearest hundreth/tenth/thousanth/etc. and estimate how many times the numerator goes into the denominator (call that number a) then take the real numerator and multiply it by your "a" adjust the number so if you add one more a to it, it will go over the denominator. Write- aww man I am a fail at this. Somebody take over. At least I tried right?

Graziella (grazia) Okay so first things first:

25 ÷ 425


you have your dividend and the divisor

for example: The divisor is the number you use to divde(25) the other number and the dividend is the number you going to divide.

To start you look at the first number of the dividend (4) we want to divide 4 by 25. How many times does four go into 25? 0 times

0____
25|425

now you multiply 25 x 0 that equals 0

0____
25|425
0
----


next you subtract 4-0 and you will get 4

0____
25|425
0
----
42

you place the 4 under the 4 and 0 like so. You bring down the number 2 now.

Now you have to divide 42 by 25 ( 42 ÷ 25) and you will get 1 and 17 remainder. ( ignore the remainders at this point) Place the 1 at the top of the

42

Next Multiply 25 x 1 to get 25

next subtract: 42-25 = 17

Now bring down the five

175

Now you want to divide 175 ÷25 = 7 and zero remainder.

25|425

42
25-

175
175-
--------
000

Next multiply 7 x 25 = 175 place 175 under the 175 and subtract 175-175= 000.

Therefore the answer must be 17 or if you want to be technical...017. :)

I hope this helps...
