Question

What is -7.5 rounded to the nearest whole number

Answer 1

Answer:

-7.5 to -8

Step-by-step explanation:

The answer is -8 because you rounded to the nearest ones place. The 7 in the ones place rounds up to 8 because the digit to the right in the tenths place is 5.

-8

When the digit to the right is 5 or greater we round away from 0.

-7.5 was rounded down and away from zero to -8.

Answer 2

Answer:

$\boxed{\bf{-8}}$

Step-by-step explanation:

The concept of this question is:

⇒ Rounding numbers

The rules for rounding are:

If the digit we're rounding to is followed by a digit less than 5, we round down and drop the digit: 2.52 => 2.5

If the digit we're rounding to is followed by a digit greater than or equal to 5, we round up: 2.25 => 2.3

Now let's try and round -7.5.

Here -7 is followed by 5 so we round up:

$\bf{-7.5 = > -8}$

Therefore, our answer is -8.
