Questions and Answers

答案:C

解答

步骤1

$\frac{5}{3}$ ÷ 2 = $\frac{5}{3}$ ÷ $\frac{2}{1}$

步骤2

将除法改写为乘法运算

$\frac{5}{3}$ ÷ $\frac{2}{1}$ = $\frac{5}{3}$ × $\frac{1}{2}$ = $\frac{(5×1)}{(3×2)}$ = $\frac{5}{6}$

步骤3

所以,$\frac{5}{3}$ ÷ 2 = $\frac{5}{6}$

答案:B

解答

步骤1

8 ÷ $\frac{4}{6}$ = $\frac{8}{1}$ ÷ $\frac{4}{6}$

步骤2

将除法改写为乘法运算

$\frac{8}{1}$ ÷ $\frac{4}{6}$ = $\frac{8}{1}$ × $\frac{6}{4}$ = $\frac{(8×6)}{(1×4)}$ = $\frac{48}{4}$ = $\frac{12}{1}$

步骤3

所以,8 ÷ $\frac{4}{6}$ = $\frac{12}{1}$ = 12

答案:A

解答

步骤1

$\frac{4}{9}$ ÷ 2 = $\frac{4}{9}$ ÷ $\frac{2}{1}$

步骤2

将除法改写为乘法运算

$\frac{4}{9}$ ÷ $\frac{2}{1}$ = $\frac{4}{9}$ × $\frac{1}{2}$ = $\frac{(4×1)}{(9×2)}$ = $\frac{4}{18}$ = $\frac{2}{9}$

步骤3

所以,$\frac{4}{9}$ ÷ 2 = $\frac{2}{9}$

答案:D

解答

步骤1

9 ÷ $\frac{3}{5}$ = $\frac{9}{1}$ ÷ $\frac{3}{5}$

步骤2

将除法改写为乘法运算

$\frac{9}{1}$ ÷ $\frac{3}{5}$ = $\frac{9}{1}$ × $\frac{5}{3}$ = $\frac{(9×5)}{(1×3)}$ = $\frac{45}{3}$ = $\frac{15}{1}$

步骤3

所以,9 ÷ $\frac{3}{5}$ = $\frac{15}{1}$ = 15

答案:B

解答

步骤1

$\frac{9}{7}$ ÷ 3 = $\frac{9}{7}$ ÷ $\frac{3}{1}$

步骤2

将除法改写为乘法运算

$\frac{9}{7}$ ÷ $\frac{3}{1}$ = $\frac{9}{7}$ × $\frac{1}{3}$ = $\frac{(9×1)}{(7×3)}$ = $\frac{9}{21}$ = $\frac{3}{7}$

步骤3

所以,$\frac{9}{7}$ ÷ 3 = $\frac{3}{7}$

答案:C

解答

步骤1

5 ÷ $\frac{10}{3}$ = $\frac{5}{1}$ ÷ $\frac{10}{3}$

步骤2

将除法改写为乘法运算

$\frac{5}{1}$ ÷ $\frac{10}{3}$ = $\frac{5}{1}$ × $\frac{3}{10}$ = $\frac{(5×3)}{(1×10)}$ = $\frac{15}{10}$ = $\frac{3}{2}$

步骤3

所以,5 ÷ $\frac{10}{3}$ = $\frac{3}{2}$

答案:A

解答

步骤1

$\frac{6}{9}$ ÷ 4 = $\frac{6}{9}$ ÷ $\frac{4}{1}$

步骤2

将除法改写为乘法运算

$\frac{6}{9}$ ÷ $\frac{4}{1}$ = $\frac{6}{9}$ × $\frac{1}{4}$ = $\frac{(6×1)}{(9×4)}$ = $\frac{6}{36}$ = $\frac{1}{6}$

步骤3

所以,$\frac{6}{9}$ ÷ 4 = $\frac{1}{6}$

答案:D

解答

步骤1

6 ÷ $\frac{5}{7}$ = $\frac{6}{1}$ ÷ $\frac{5}{7}$

步骤2

将除法改写为乘法运算

$\frac{6}{1}$ ÷ $\frac{5}{7}$ = $\frac{6}{1}$ × $\frac{7}{5}$ = $\frac{(6×7)}{(1×5)}$ = $\frac{42}{5}$

步骤3

所以,6 ÷ $\frac{5}{7}$ = $\frac{42}{5}$

答案:C

解答

步骤1

$\frac{5}{6}$ ÷ 4 = $\frac{5}{6}$ ÷ $\frac{4}{1}$

步骤2

将除法改写为乘法运算

$\frac{5}{6}$ ÷ $\frac{4}{1}$ = $\frac{5}{6}$ × $\frac{1}{4}$ = $\frac{(5×1)}{(6×4)}$ = $\frac{5}{24}$

步骤3

所以,$\frac{5}{6}$ ÷ 4 = $\frac{5}{24}$

答案:B

解答

步骤1

7 ÷ $\frac{8}{6}$ = $\frac{7}{1}$ ÷ $\frac{8}{6}$

步骤2

将除法改写为乘法运算

$\frac{7}{1}$ ÷ $\frac{8}{6}$ = $\frac{7}{1}$ × $\frac{6}{8}$ = $\frac{(7×6)}{(1×8)}$ = $\frac{42}{8}$= $\frac{21}{4}$

步骤3

所以,7 ÷ $\frac{8}{6}$ = $\frac{21}{4}$
