What must be done after multiplying across?

Simplify by dividing both parts by their common factors.

Why is 1/4 of 8 equal to 2?

8 is a multiple of 4, so one of four equal parts is 2.

03　Answers and one-line notes

#	Answer	One-line note
1	6/5, that is 1 1/5	When a fraction is multiplied by an integer the denominator stays, only the numerator is multiplied: 2 × 3 = 6.
2	2	8 divides exactly by 4, so each of the four parts is 2.
3	6/7	The denominator stays 7 while the numerator becomes 3 × 2 = 6.
4	1/2	Multiply across to get 6/12, then simplify to 1/2.
5	1/4	The product is 15/60, and dividing both parts by 15 gives 1/4.
6	3	Change the mixed number to 3/2 first, then multiply by 2 to get 3.
7	4	As improper fractions they are 8/3 and 3/2, and the product 24/6 is 4.
8	1/6	Cancel first: 4 and 8 share 4, 3 and 9 share 3, leaving 1/3 × 1/2 = 1/6.
9	15/4 kg, that is 3 3/4 kg	Each cake is 3/4 kg, so five cakes weigh 3/4 × 5 = 15/4 kg.
10	1/2	6/12 is not in simplest form; dividing both parts by 6 gives 1/2.

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.
