What is 4 over 9 in decimals?

Answer 1

Use long division:

dividend = 4.000...

divisor = 9

quotient = answer

(a) 9 won't go into 4 (it goes in 0 times, remainder 4)

(b) put 0 in the quotient, to left of decimal point

(c) Pull down a zero (from dividend), appending it to 4 to make 40.

(d) 9 goes into 40 ? Yes, 4 times, remainder 4.

(e) Put a 4 to right of previous digit of quotient

(f) GOTO (c)

The algorithm is an infinite loop, generating a periodic decimal:

0.444...

This is the answer.
