There are three numbers a, b, c, where a > b and b >c. Describe the positions of the numbers on a number line.
AfilCa [17]
In maths, the “>” sign means “greater than”, or “bigger than.” If we say A > B, that means (in English) “A is bigger than B.”
So, if A > B and B > C:
A is bigger than B, and B is bigger than C.

So the smallest would be C, since both A and B are bigger. Next is B, and biggest is A.

That is the order they would be in a number line: C - B - A

harina [27]

Answer:

-

Step-by-step explanation:

Rule for rounding :

You look at the number next to the place value you are meant to round and if the number is :

=

4 and below you round down.

5 and above you round up

Nearest hundred thousand: 100,000

This is because you look at the number next to the hundred thousand spot which is a 2 so you round down

Nearest ten thousand: 130,000

Same reason as before the number next to the 2 in the number is a 6. So you round up

Nearest thousand: 126,000

The number next to the thousandth place value is a 0 so you round down
