Question

18 : 24. 1 1/4 : 2 2/3. 1/3 : 1/7. 10:15:40

Answer 1

18 : 24=0,75

$\frac{11}{4} : 2\frac{2}{3} \\\frac{11}{4} *\frac{1}{2} *\frac{2}{3} \\\frac{11}{4} *\frac{1}{3} \\\frac{11}{12}$

1/3 : 1/7

$\frac{1}{3} : \frac{1}{7} \\\frac{1}{3} *7\\\frac{7} {3}$

10:15:40

$\frac{10}{15} *\frac{1}{40} \\\frac{1}{15} *\frac{1}{4} \\\frac{1}{60}$

Answer 2

Пошаговое объяснение:

18 : 24 = 18/24 = 3/4

1 1/4 : 2 2/3 = 5/4 : 8/3 = 5/4 * 3/8 = 15/32

1/3 : 1/7 = 1/3 * 7/1 = 7/3 = 2 1/3

10 : 15 : 40 = 10/15 * 1/40 = 1/15 * 1/4 = 1/60
