Answer 2

ratios are dependent on each other like twevle cups of flour to two cups of sugar or something like the so for percentages
Ex. 75% would be 75:100 because it is out of a hundred percent and this reduces down to 3:4 read a fraction is a ratio so all you have to do is reduce it and change decimals into fractions and solving from there

Answer 3

percentages (%) = 100 ths.
25% means 25 hundredths of so 25% 0f 300 is worked out by:1st dividing 300 by 100 this gives you 1/100. If you them multiply this by 25 you have 25 100ths. Here the answer is 75.

Decimal numbers are all numbers we use in normal maths. The base is 10, hence decimal. As numbers increase in powers of 10 as you move to the left. they decrease in 10ths as you move to the right.

Fractions, You must know what these are so, what do you wish to know about them.

What was your "masters" in? I hope it wasn't maths.
