11. Numerals: 27
Words: twenty-seven
Explanation: Count by grouping: first row 10, second row 10, third row 7. 10 + 10 + 7 = 27. Write in words: "twenty-seven" (hyphen between twenty and seven).
Marking: 1 mark for correct numeral, 1 mark for correct spelling in words.

12. (a) 63 = 6 tens 3 ones
(b) 80 = 8 tens 0 ones
