The rational numbers can be expressed in two forms: the fraction form and the decimal form.
For example, the number 1/2 is in the fraction form, and the corresponding decimal form is 0.5.
To find the decimal form, you just need to divide the numerator by the denominator.
So, to find the number 3/4 in its decimal form, we need to divide 3 by 4.
As 3 is lesser than 4, we need to put a 0 in front of it, so it becames a 30, but then our answer starts to be a decimal number (the first digit before the comma will be a zero, as 3 divided by 4 initially is 0).
Then, dividing 30 by 4, we have 7, and the rest is 2.
So our decimal answer until now is 0.7
Now, with the rest 2, we put another zero, and the answer advance to the second decimal place.
Now, dividing 20 by 4, we have 5, and rest 0.
this result of 5 will be the second decimal place, so our result is 0.75.
That means 0.75 is the decimal form of the number 3/4
