Answer:
Step-by-step explanation:
1) 6 1/2 ÷ 2 2/3 = 13/2 ÷ 8/3 = 13/2 x 3/8 = 39/16 = 2 [tex]\frac{7}{16}[/tex]
2) 3 2/7 ÷ 1 1/4 = 23/7 ÷ 11/4 = 23/7 x 4/11 = 92/77 = 1 [tex]\frac{15}{77}[/tex]
3. 1 3/8 ÷ 1 1/12 = [tex]\frac{1×8+3}{8} : \frac{1×12+1}{12}[/tex] = [tex]\frac{11}{8} : \frac{13}{12}[/tex] = [tex]\frac{11}{8} × \frac{12}{13}[/tex] = [tex]\frac{11x3x4}{2x4x13}[/tex] = 33/26 = 1 [tex]\frac{7}{26}[/tex]
4. 1 3/8 × 3 1/3 = 11/8 x 10/3 = 110/24 = 4 [tex]\frac{7}{12}[/tex]
5. 1 1/3 × 2 1/5 = 4/3 x 11/5 = 44/15 = 2 [tex]\frac{14}{15}[/tex]
6. 1 3/4 × 2 2/3 = 7/4 x 8/3 = 56/12 = 4 [tex]\frac{2}{3}[/tex]
