Question

The lowest temperature ever recorded in North America was -63°C. The lowest temperature ever recorded in South America was –32.8°C. Was the South America temperature warmer or colder, and by how many degrees?

Answer 1

Answer:

South America was warmer by 30.2°

Step-by-step explanation:

When we see this question properly we get to know that both are negative numbers.

And we know that in negative numbers the sign matters a lot.

In negative numbers the number which is smaller is greater and the number which is smaller is bigger.

Like lets take an example of -2 and -3

We know that 3 is larger than 2 but as it is negative numbers here so -2 will be greater than -3.

Now,

If the temperature in the lowest temperature ever recorded in North America was -63°C. The lowest temperature ever recorded in South America was –32.8°C.

So,

$- 32.8 > - 63$

So the temperature in South america was warmer.

Now,

By how much was it warmer??

To find how much more hot it was we can subtract the colder temperature from the warmer temperature. Like this

$- 32.8 - ( - 63)$

$= - 32.8 + 63.0$

$= 30.2$

So the temperature of South america was warmer by 30.2° C.

Hope it helps you!

Answer:

  warmer by 30.2 degrees

Step-by-step explanation:

It might help to think of these values plotted on a number line. Both temperatures will be left of zero, with -63°C being farther to the left (colder).

The difference can be found by subtracting the colder temperature from the warmer one:

  -32.8 -(-63) = -32.8 +63 = 63 -32.8 = 30.2 . . . degrees

The South America temperature -32.8°C is 30.2° warmer than the North America temperature.
