75p=500g
therefore
150p=1000g
(double both sides)
100g is 1000 divided by 10.
Then do the same with the 150p:
150 divided by 10 is 15p.
If 100g is 15p, then 300g is 45p (100*3 is 300, then do the same to the 15p)
To work out 0.1 and 0.4 as percentages, just multiply them by 100!

1/2 kg is 500 g...so 75p for 500g...
then for 1g it will be 500g divided by 75 p that is..6.66 or 6.7 paise approximately...then for 100g it will be 6.66 multiplied by 100 that is 666 paise or 6 rupees and 66paise...
for 300g it will be 6.66 multiplied by 300 which is 1998 paise which also is 19 rupees and 98 paise
0.1 as % is 1 upon 10 in 100 that is 10
and 0.4 is actually 4 upon 10...then multiply by 100 and it is 40

100g = 1/5x75 = 15p
300g = 3 x the above = 45p
0.1 = 10%
0.4 = 40%

People have already answered your questions but I don't think these are that difficult really. Maybe you need to tell your teacher you're having difficulties.

These are ridicoulously easy questions.
If you had been only half paying attention you should be able to do it yourself.
If you cant manage these questions then you need to tell the teacher, you will need some special help.
