Explanation

(a) Convert 3/10 to 30/100, then add: 30/100 + 304/100 = 334/100 = 3.34 (b) Add whole numbers: 9 + 2 = 11. Add fractions: 57/100 + 13/100 = 70/100 = 7/10. Result: 11.7 (c) Add: 15.64 + 14.36 = 30.00 (d) Subtract: 7.07 - 4.04 = 3.03 (e) Subtract: 8.06 - 5.03 = 3.03 (f) Convert: 12.62 - 0.99 = 11.63
