Question

Randy's gas tank is 5/8 full.after driving around all day he he used 3/8 of his gas.what fraction of Randy's gas tank is full now?

Answer 1

The fraction of Randy's gas tank is full now = 2/5

Step-by-step explanation:

Randy's full gas tank = 5/8

After driving, he used = 3/8

Therefore, the remaining gas in the tank= gas in full tank - used gas

                                   The remaining gas = 5/8 - 3/8= 2/8

The fraction of gas tank full now = remaining gas / full gas

                                                      = (2/8) / (5/8)

                                                      = (2/8)*(8/5) = 2/5
