Lydia spent 4/5 of her money on a mobile phone and 2/3 of the remaining amount on a bag. she had $60 left. how much more money did she spend on the mobile phone than on the bag?

The answer is 600 because 1 out 3 is 60 so to find the bag multiply by two while to find 1 out 5 of her monet take 60 times 3 which is 180. 180 times 4 is the money she spent on her mobile phone so take the money spent on her mobile phone(720)minus the amount of money spent on the bag(120)
