03　Answers and one-line notes

#	Answer	One-line note
1	9/20.	Divide 45 and 100 by 5 to get 9/20, which cannot be simplified further.
2	4/25.	Divide 16 and 100 by 4 to get 4/25; 4 and 25 share no further factor.
3	35%.	Multiply the top and bottom by 5: 7/20 = 35/100, which is 35%.
4	7%.	0.07 x 100 = 7; move the decimal point two places to the right.
5	60.	150 x 0.4 = 60; you can also take 10% of 150 as 15 and multiply by 4.
6	25%.	Divide the part by the whole: 60 / 240 = 0.25, that is 25%.
7	21.	60 x 0.35 = 21; turn the percentage into a decimal first.
8	3/8 is larger.	3/8 = 0.375 while 35% = 0.35, and 0.375 is greater; convert both to the same form first.
9	0.6, 62%, 5/8.	As decimals they are 0.6, 0.625 and 0.62, so the order is 0.6, 62%, 5/8.
10	The answer is 50.	Turn 25% into 0.25 before multiplying: 200 x 0.25 = 50; multiplying by 25 inflates the result a hundredfold.

04　What to do after marking

After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
Repeat the same item two days later; move to the next paper only when both attempts are correct.
Parents only need the answer and note columns; there is no need to explain every item.

Ask first what whole a percentage is taken from. When the question says “of”, multiply; when it asks what fraction one value is of another, divide the part by the whole. The percent sign is notation only, so the decimal is what does the work. Convert to decimals or fractions before comparing, and multiply step by step for two successive changes instead of adding the percentages.Tutor Registration →
