pls help - maths( steps and answer).........thank you!!!!
1.) Two months ago, the total weight of Leo and Wilson was 130 kg. They went to a fitness centre together for physical training.
Now, the weight of Leo drops by 1/4 and the weight of Wilson drops by 2/7.
If Leo weight 5 kg less than Wilson at present,
