6. Find the sums and differences:

A The answer is: 15/7 + 6/100 + 4/100 = 15/7 + 10/100 = 15/7 + 0.1; 14/7 + 3/100 + 6/100 - 4/100 = 14/7 + 9/100 - 4/100 = 14/7 + 5/100 = 14/7 + 0.05 (Students need to calculate the exact sums and differences). B The answer is: 15/7 + 6/100 + 4/100 = 15/7 + 12/100 = 15/7 + 0.12; 14/7 + 3/100 + 6/100 - 4/100 = 14/7 + 5/100 - 4/100 = 14/7 + 1/100 = 14/7 + 0.01 (Students need to calculate the exact sums and differences). C The answer is: 15/7 + 6/100 + 4/100 = 15/7 + 8/100 = 15/7 + 0.08; 14/7 + 3/100 + 6/100 - 4/100 = 14/7 + 7/100 - 4/100 = 14/7 + 3/100 = 14/7 + 0.03 (Students need to calculate the exact sums and differences). D The answer is: 15/7 + 6/100 + 4/100 = 15/7 + 14/100 = 15/7 + 0.14; 14/7 + 3/100 + 6/100 - 4/100 = 14/7 + 11/100 - 4/100 = 14/7 + 7/100 = 14/7 + 0.07 (Students need to calculate the exact sums and differences).

7. Identify and write the decimal numbers against the letters.

A A: 5.1, B: 5.2, C: 5.3, D: 5.4 B A: 5.4, B: 5.3, C: 5.2, D: 5.1 C A: 5.2, B: 5.1, C: 5.4, D: 5.3 D A: 5.3, B: 5.4, C: 5.1, D: 5.2

8. Convert the following fractions into decimals: (a) 5/100 (b) 16/1000
