Question

round 0.147 to the 1 significant figure.

Answer 1

Answer:

Rounding 0.147 to 1 significant figure, we get 0.2

Step-by-step explanation:

Number = 0.147

We need to round it to the 1 significant figure, it means after decimal, there should only be 1 digit.

Steps to round off: if the left most digit is more than equal to 5, the digit immediate next to left most digit is increased by 1 and if less than 5, then the digit is kept same.

Now, 0.147

First check the left most digit, which is 7 and is greater than 5

Thus, 0.147 = 0.15

Again 5 is equal to 5

Thus, 0.15 = 0.2

Rounding 0.147 to 1 significant figure, we get 0.2

Answer 2

Answer:

0.1

Step-by-step explanation:

Original Answer = 0.147

(don't forget to put the line from one significant figure.)

0.1 || 47

Is the hundredth digit more than 5?

If yes tenth digit must be estimated as 2

If no tenth digit must be estimated as 1

(It is just a different way of rounding of a particular number.)

the hundredth digit is less than 5, so the tenth digit remains the same, but we can estimate and ignore hundredth and thousandth digit.
