Problem 1: 23×315\frac{2}{3} \times \frac{3}{15}
Multiply the numerators and denominators:
2×33×15=645\frac{2 \times 3}{3 \times 15} = \frac{6}{45}
Simplify the fraction by dividing both numerator and denominator by their greatest common divisor, which is 3:
6÷345÷3=215\frac{6 \div 3}{45 \div 3} = \frac{2}{15}
Problem 2: 58×720\frac{5}{8} \times \frac{7}{20}
Multiply the numerators and denominators:
5×78×20=35160\frac{5 \times 7}{8 \times 20} = \frac{35}{160}
Simplify the fraction by dividing both numerator and denominator by their greatest common divisor, which is 5:
35÷5160÷5=732\frac{35 \div 5}{160 \div 5} = \frac{7}{32}
Problem 3: 45×810\frac{4}{5} \times \frac{8}{10}
Multiply the numerators and denominators:
4×85×10=3250\frac{4 \times 8}{5 \times 10} = \frac{32}{50}
Simplify the fraction by dividing both numerator and denominator by their greatest common divisor, which is 2:
32÷250÷2=1625\frac{32 \div 2}{50 \div 2} = \frac{16}{25}
Problem 4: 1030×310\frac{10}{30} \times \frac{3}{10}
Multiply the numerators and denominators:
10×330×10=30300\frac{10 \times 3}{30 \times 10} = \frac{30}{300}
Simplify the fraction by dividing both numerator and denominator by their greatest common divisor, which is 30:
30÷30300÷30=110\frac{30 \div 30}{300 \div 30} = \frac{1}{10}
Problem 5: 28×515\frac{2}{8} \times \frac{5}{15}
Multiply the numerators and denominators:
2×58×15=10120\frac{2 \times 5}{8 \times 15} = \frac{10}{120}
Simplify the fraction by dividing both numerator and denominator by their greatest common divisor, which is 10:
10÷10120÷10=112\frac{10 \div 10}{120 \div 10} = \frac{1}{12}
Problem 6: 1216×620\frac{12}{16} \times \frac{6}{20}
Multiply the numerators and denominators:
12×616×20=72320\frac{12 \times 6}{16 \times 20} = \frac{72}{320}
Simplify the fraction by dividing both numerator and denominator by their greatest common divisor, which is 8:
72÷8320÷8=940\frac{72 \div 8}{320 \div 8} = \frac{9}{40}
Problem 7: 3040×1011\frac{30}{40} \times \frac{10}{11}
Multiply the numerators and denominators:
30×1040×11=300440\frac{30 \times 10}{40 \times 11} = \frac{300}{440}
Simplify the fraction by dividing both numerator and denominator by their greatest common divisor, which is 20:
300÷20440÷20=1522\frac{300 \div 20}{440 \div 20} = \frac{15}{22}
Problem 8: 1530×412\frac{15}{30} \times \frac{4}{12}
Multiply the numerators and denominators:
15×430×12=60360\frac{15 \times 4}{30 \times 12} = \frac{60}{360}
Simplify the fraction by dividing both numerator and denominator by their greatest common divisor, which is 60:
60÷60360÷60=16\frac{60 \div 60}{360 \div 60} = \frac{1}{6}
