On the number line, less then a quarter of a unit to the left.

Step-by-step explanation:

The number is is bit smaller then zero. Consider the temperature. When it is freezing, you can get temperatures below zero. If it freezes 1 degree that would be 1 unit to the left of zero on the number line.

However, we have a temperature of just 0.2 below zero, so on the number line, that is less then a quarter of a unit to the left.

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
