My friend's bike has 10 liters of petrol. My bike has 5 liters less. How many liters of petrol does my bike have?

If you can solve this example, then set up your exercise the same way.

If you still need help, please show us what you've tried or thought about, so far. Cheers!

As Otis strongly hinted, when you have trouble knowing how to solve a problem with the given numbers then try to use friendlier numbers.A man uses 5/2 buckets of paint to paint a Hall. He uses 5/4 less buckets to paint a room. How much paint did he use for the room?

Try to answer this one: A man uses 8 buckets of paint to paint a Hall. He uses 3 less buckets to paint a room. How much paint did he use for the room?

Yes... Right. Thank you."less" indicates some sort of subtraction or reduction. What are your thoughts?

Thank you for this good example. It helped.

Thank you so much... All examples are very helpful.As Otis strongly hinted, when you have trouble knowing how to solve a problem with the given numbers then try to use friendlier numbers.

Sure. Right. People on this forum helped me understand.So what was your answer? Even if you know it is correct please post it anyways so other having the same trouble can see how you worked it out.

The paint used for hall = 5/2 buckets.

The paint used for room = 5/4 less buckets.

Therefore 5/2 - 5/4 = 5/4 or 1 1/4

Thank you.
