here is the gauge for the fuel tank of a car. the tank holds 68 litres when the tank is full. the tank is 1/4 full of fuel work out how many more litres of fuel is needed to fill the tank

51 liters of fuel is needed more to fill the tank

Step-by-step explanation:

When the gauge is full, the volume of fuel in the tank is 68 liters.

Now it is 1/4 full.

The amount of fuel it has when it is 1/4 full would be 1/4 * 68 = 17 liters

Now, we need to know how many more liters of fuel until the tank is full.

What we just need to do here is to subtract the volume when it is quarter full from the volume when it is full.

That would be 68 liters - 17 liters = 51 liters

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?
