LenaWriter [7]

Answer:

Option 3 - 0 point 5.

Step-by-step explanation:

Given : Decimal equivalent of 5 over 9.

To find : Use long division to determine the decimal?

Solution :

We have to divide 5 by 9,

Step 1 - Divide 5 by 9 as it is not divisible put a decimal and 0 after 5,

Step 2 - Now, divide 50 by 9 the quotient is 5 and remainder is 5.

Step 3 - Again put 0 and divide the number repeat the process until the remainder is not zero.

We have done the calculation up to 3-decimal place.

So, \frac{5}{9}=0.555

Approximately, \frac{5}{9}=0.5

So, Option 3 is correct.

Refer the attached figure for calculation.
