Question

What is 0.64 rounded to the tenth place?
a) 0.6
b) 0.7
c) 0.64
d) 0.60

Answer 1

When rounding 0.64 to the tenth place, since the hundredths place has a 4, which is less than 5, we do not round up, resulting in 0.6. The correct answer is a) 0.6.

Step-by-step explanation:

Rounding a number involves approximating it to a specified place value or significant digits. This can be done using various rounding methods:

Rounding to a Specific Decimal Place:

For example, to round 3.14159 to two decimal places:

If the digit immediately after the second decimal place is 5 or more, round up; if it's less than 5, round down.

So, 3.14159 rounded to two decimal places is 3.14.

The question is asking to round the number 0.64 to the tenth place. To round to the tenth place, look at the digit in the hundredths place, which is a 4 in this case. Since the digit is less than 5, we do not round up the tenths place. Therefore, rounding 0.64 to the tenth place gives us 0.6.
