Question

Find the rational number halfway between the two numbers below.
-1/3 and -3/10

Answer 1

-19/60

Explanation:

You want the rational number halfway between -1/3 and -3/10.

Average value

The average of two numbers is the number halfway between them. It is their sum, divided by two.

Effectively, you are being asked for the average of -1/3 and -3/10.

`\text{average }=\left(-(1)/(3)-(3)/(10)\right)*(1)/(2)=-(1\cdot10+3\cdot3)/(3\cdot10\cdot2)=\boxed{-(19)/(60)}`
