The gas tank of wendy’s car was 23 full. she used 16 of a tank of gas when driving to and from work. which equation shows how full the gas tank is now? 23−26=13 tank 26−23=13 tank 23−16=12 tank 16−23=12 tank

The 3rd choice: 2/3 tank - 1/6 tank = 1/2 tank

Step-by-step explanation:

I assume those numbers are fractions.

The gas tank of Wendy’s car was 2/3 full. She used 1/6 of a tank of gas when driving to and from work. Which equation shows how full the gas tank is now?

We subtract 1/6 from 2/3. We need to use the common denominator 6.

2/3 - 1/6 = 4/6 - 1/6 = 3/6

Now we reduce 3/6.

2/3 - 1/6 = 1/2

2/3 tank - 1/6 tank = 1/2 tank
