Answer 1

Answer:

0.432 is your answer please follow me

Answer 2

Answer:

0.43

Step-by-step explanation:

To convert a rational number to decimal, we just have to divide 18/42.

So, 18/42 gives 0.4285......

So, to make things simple, the answer is rounded off at the 2nd decimal place.

To round a decimal number, look at the digit right next to the digit you want to round off. Then see whether that digit is 5 or above. If it is 5 or above, change the digit to the left by 1.

So, in this case, I see the 2nd digit after the decimal point (which is 2) and see the next digit after that (which is 8). So, as 8 is a digit which is bigger than 5, I change the 2nd digit by 1. So, instead of 2, I change it to 3.

So your answer is 0.43.
