Question

2.34 is obtained by rounding off the number

Answer 1

Explanation:

Given 2.34 is obtained by rounding off the number

• So we need to find by taking the options.
• So the first option is 2.346
• Now we need to find the rounding off this number.
• Rounding off is to take the approximation.
• So if we round off this number twice we get in two cases 2.35 and 2.34
• So which is more approximate so we can choose that number.
• Here if we take the difference of 2.346 and 2.35 we get 0.004 and  
• the difference between 2.346 and 2.34 we get 0.006
• so we can choose the number 2.35 and so it is not possible.
• Now consider second option it is 2.355
• If we take two nearest numbers 2.36 and 2.35 and the difference between the two is 0.005.
• So in the number 2.355, check the tens digit, if it is odd add 1 and if it is even subtract 1. Here the digit is odd, so we can choose 2.36
• Now consider the third option it is 2.335 and tens digit is odd , so we get 2.34
• Now consider the fourth option it is 2.334 and consider two nearest numbers we get 2.33 and 2.34
• So the difference will be 0.004 and 0.006 and so we get 2.34
• So consider the option 3, it is 2.34, if we need to round off, if the ones digit is greater than 5 add 1 and if it is less than 5 subtract 1.
• So we get the correct option as 2.335

Answer 2

Explanation:

the answer is simple

given number is 2.346

now,

we should minus one number in last digit

2.346 = 2.345

again we should minus one number in last second digit

2.345 = 2.335

so the rounding of the number 2.34 is

2.335
