In one week Holly works twice as long as Wei-Kong and Wei-Kong works for three times as many hours as Wilfred. Their total wages that week is £850. Work out how much Hollie receives. (2 marks)

Question 1:

Connor : Patrick = 8 : 9
Total Parts = 8 + 9 = 17 
17 parts = 153 kg

Find 1 parts:
1 part = 153 ÷ 17 = 9kg

Find 8 parts:
8 parts = 8 x 9 = 72kg

Find 9 parts:
9 parts = 9 x 9 = 81 kg

Connor : Patrick = 8 : 9 = 72kg : 81 kg

81 - 72 = 9kg

Answer: Partick is 9 kg heavier than Connor.

Question 2:

Tim and Savannah  = 1 : 2
2 parts = 50 sweets

Find 1 part :
1 part = 50 ÷ 2 = 25

Answer: Tim gets 25 sweets

Question 3:

Holly : Wei Kong : Wilfred
     6  :         3       :     1

Total Parts = 6 + 3 + 1 = 10
10 parts = ⇒£850

Find 1 part :
1 part = £850 ÷ 10 = £85

Find 6 parts :
6 parts = £85 x 6 = £510

Answer: Hollie receives  £510
