1. Calculate the sum of 18 and 12%. First, express 12% as a decimal: $$12\% = \frac{12}{100} = 0.12$$ Next, multiply 18 by 0.12 to find 12% of 18: $$18 \times 0.12 = 2.16$$ Finally, add this to 18: $$18 + 2.16 = 20.16$$ So, the sum of 18 and 12% of 18 is 20.16. 2. Irene has 34 buttons and Sira has 29. How many buttons do they have together with duplicates? Add the number of buttons: $$34 + 29 = 63$$ They have 63 buttons in total considering duplicates. 3. Luke has 12 marbles in one box and 8 marbles in another. Catherine has many marbles summer than Luke. (This problem seems unclear due to possible typo. Assuming it wants to find how many marbles Luke has in total.) Add Luke's marbles: $$12 + 8 = 20$$ Luke has 20 marbles in total. 4. Fill in the apples. HL fruit pies. How many? (This problem is ambiguous and incomplete - no numbers or further info is given.) Since the graph shows four apples of different sizes and colors, likely the total number of apples is 4. Final answers: 1) 20.16 2) 63 3) 20 4) 4
