Questions:

  1. 23×6\frac{2}{3} \times 6
  2. 4÷254 \div \frac{2}{5}
  3. 314+2233 \frac{1}{4} + 2 \frac{2}{3}
  4. 81\sqrt{81}
  5. 32+423^2 + 4^2
  6. 9(4+3)9 - (4 + 3)
  7. 643\sqrt[3]{64}
  8. 1.5÷0.51.5 \div 0.5

Solutions:

  1. 23×6\frac{2}{3} \times 6: 23×6=2×63=123=4\frac{2}{3} \times 6 = \frac{2 \times 6}{3} = \frac{12}{3} = 4 Answer: 4

  2. 4÷254 \div \frac{2}{5}: 4÷25=4×52=4×52=202=104 \div \frac{2}{5} = 4 \times \frac{5}{2} = \frac{4 \times 5}{2} = \frac{20}{2} = 10 Answer: 10

  3. 314+2233 \frac{1}{4} + 2 \frac{2}{3}: Convert mixed numbers to improper fractions: 314=134,223=833 \frac{1}{4} = \frac{13}{4}, \quad 2 \frac{2}{3} = \frac{8}{3} Find a common denominator (12): 134=3912,83=3212\frac{13}{4} = \frac{39}{12}, \quad \frac{8}{3} = \frac{32}{12} Add the fractions: 3912+3212=39+3212=71125.92\frac{39}{12} + \frac{32}{12} = \frac{39 + 32}{12} = \frac{71}{12} \approx 5.92 Answer: 7112\frac{71}{12} or approximately 5.92

  4. 81\sqrt{81}: 81=9\sqrt{81} = 9 Answer: 9

  5. 32+423^2 + 4^2: 32+42=9+16=253^2 + 4^2 = 9 + 16 = 25 Answer: 25

  6. 9(4+3)9 - (4 + 3): 9(4+3)=97=29 - (4 + 3) = 9 - 7 = 2 Answer: 2

  7. 643\sqrt[3]{64}: 643=4\sqrt[3]{64} = 4 Answer: 4

  8. 1.5÷0.51.5 \div 0.5: 1.5÷0.5=1.50.5=31.5 \div 0.5 = \frac{1.5}{0.5} = 3 Answer: 3
