Question

1. 6 1/2 ÷ 2 2/3=?

Answer 1

Answer:

Step-by-step explanation:

1) 6 1/2 ÷ 2 2/3 = 13/2 ÷ 8/3 = 13/2 x 3/8 = 39/16 = 2 $\frac{7}{16}$

2) 3 2/7 ÷ 1 1/4 = 23/7 ÷ 11/4 = 23/7 x 4/11 = 92/77 = 1 $\frac{15}{77}$

3. 1 3/8 ÷ 1 1/12 = $\frac{1×8+3}{8} : \frac{1×12+1}{12}$ = $\frac{11}{8} : \frac{13}{12}$ = $\frac{11}{8} × \frac{12}{13}$ = $\frac{11x3x4}{2x4x13}$ = 33/26 = 1 $\frac{7}{26}$

4. 1 3/8 × 3 1/3 = 11/8 x 10/3 = 110/24 = 4 $\frac{7}{12}$

5. 1 1/3 × 2 1/5 = 4/3 x 11/5 = 44/15 = 2 $\frac{14}{15}$

6. 1 3/4 × 2 2/3 = 7/4 x 8/3 = 56/12 = 4 $\frac{2}{3}$
