What is the order from least to greatest for these numbers
-6.3, 4.2, 7.7, -3.9, 3.4

-6.3, -3.9, 3.4, 4.2, 7.7

Step-by-step explanation:

Use the number line.

Now remember, the highest negative is last.

So -6.3 goes first, then the next negative, -3.9.

Now use the natural order of numbers, 1,2,3,4

So then continued, it would be 3.4, 4.2, 7.7

This is your

Step-by-step explanation:

Least to greatest:

NOTE:

Remember - when you are dealing with negative numbers and ordering them, the greater the negative number, the less value it has>

-6.3 has less value than -3.9 because -6.3 is a greater negative number, and because as you keep moving left on the number line, the values keep decreasing in value.

-6.3 has less value than -0.01

but

-6.3 has greater value than -6.5

I hope this helps!

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
