2 | 7 |
x | 14 |
6 | y |
8 | 28 |
答案:A
解释
步骤 1
从给定的值表中
$\frac{x}{14} = \frac{2}{7}; x = \frac{2}{7} \times \frac{14}{1} = 4$
步骤 2
$\frac{y}{6} = \frac{7}{2}; y = \frac{7}{2} \times 6 = \frac{7}{2} \times \frac{6}{1} = 21$
步骤 3
所以,$x = 4;y = 21$
4 | 9 |
8 | 18 |
12 | x |
y | 36 |
答案:C
解释
步骤 1
从给定的值表中
$\frac{x}{12} = \frac{9}{4}; x = \frac{9}{4} \times 12 = \frac{9}{4} \times \frac{12}{1} = 27$
步骤 2
$\frac{y}{36} = \frac{4}{9}; y = \frac{4}{9} \times 36 = \frac{4}{9} \times \frac{36}{1} = 16$
步骤 3
所以,$x = 27;y = 16$
3 | 10 |
6 | x |
9 | 30 |
y | 40 |
答案:B
解释
步骤 1
从给定的值表中
$\frac{x}{6} = \frac{10}{3}; x = \frac{10}{3} \times 6 = \frac{10}{3} \times \frac{6}{1} = 20$
步骤 2
$\frac{y}{40} = \frac{3}{10}; y = \frac{3}{10} \times 40 = \frac{3}{10} \times \frac{40}{1} = 12$
步骤 3
所以,$x = 20;y = 12$
2 | 9 |
4 | x |
6 | 27 |
y | 36 |
答案:D
解释
步骤 1
从给定的值表中
$\frac{x}{4} = \frac{9}{2}$;x = $\frac{9}{2} \times 4$ = $\frac{9}{2} \times \frac{4}{1}$ = 18
步骤 2
$\frac{y}{36} = \frac{2}{9}$;y = $\frac{2}{9} \times 36$ = $\frac{2}{9} \times \frac{36}{1}$ = 8
步骤 3
所以,$x = 18$;y = 8$
3 | 7 |
6 | 14 |
x | 21 |
12 | y |
答案:A
解释
步骤 1
从给定的值表中
$\frac{x}{21} = \frac{3}{7}$;x = $\frac{3}{7} \times \frac{21}{1}$ = $\frac{3}{7} \times \frac{21}{1}$ = 9
步骤 2
$\frac{y}{12} = \frac{7}{3}$;y = $\frac{7}{3} \times 12$ = $\frac{7}{3} \times \frac{12}{1}$ = 28
步骤 3
所以,$x = 9$;y = 28$
5 | 7 |
x | 14 |
15 | y |
20 | 28 |
答案:D
解释
步骤 1
从给定的值表中
$\frac{x}{14} = \frac{5}{7}$;x = $\frac{5}{7} \times 14$ = $\frac{5}{7} \times \frac{14}{1}$ = 10
步骤 2
$\frac{y}{15} = \frac{7}{5}$;y = $\frac{7}{5} \times 15$ = $\frac{7}{5} \times \frac{15}{1}$ = 21
步骤 3
所以,$x = 10$;y = 21$
2 | 3 |
4 | 6 |
6 | x |
y | 12 |
答案:B
解释
步骤 1
从给定的值表中
$\frac{x}{6} = \frac{3}{2}$;x = $\frac{3}{2} \times \frac{6}{1}$ = $\frac{3}{2} \times \frac{6}{1}$ = 9
步骤 2
$\frac{y}{12} = \frac{2}{3}$;y = $\frac{2}{3} \times 12$ = $\frac{2}{3} \times \frac{12}{1}$ = 8
步骤 3
所以,$x = 9$;y = 8$
4 | 5 |
x | 10 |
12 | y |
16 | 20 |
答案:C
解释
步骤 1
从给定的值表中
$\frac{x}{10} = \frac{4}{5}$;x = $\frac{4}{5} \times 10$ = $\frac{4}{5} \times \frac{10}{1}$ = 8
步骤 2
$\frac{y}{12} = \frac{5}{4}$;y = $\frac{5}{4} \times 12$ = $\frac{5}{4} \times \frac{12}{1}$ = 15
步骤 3
所以,$x = 8$;y = 15$
2 | 5 |
4 | 10 |
6 | x |
y | 20 |
答案:C
解释
步骤 1
从给定的值表中
$\frac{x}{6} = \frac{5}{2}$;x = $\frac{5}{2} \times 6$ = $\frac{5}{2} \times \frac{6}{1}$ = 15
步骤 2
$\frac{y}{20} = \frac{2}{5}$;y = $\frac{2}{5} \times 20$ = $\frac{2}{5} \times \frac{20}{1}$ = 8
步骤 3
