Answer 1

Пошаговое объяснение:

1)

13/24d * 32c = (13/24 * 32) * d * c =

(13/3 * 4) * dc = 52/3 * dc = 17 1/3dc

2)

6 3/4x * 1 11/45y = (6 3/4 * 1 11/45) * x * y =

(27/4 * 56/45) * xy = (3/1 * 14/5) * xy =

42/5 * xy = 8 2/5xy

3)

18 1/3a * 1 2/11b * 9/13c =

(18 1/3 * 1 2/11 * 9/13) * a * b * c =

(55/3 * 13/11 * 9/13) * abc =

(55/3 * 1/11 * 9/1) * abc = (55/3 * 9/11) * abc =

(5/1 * 3/1) * abc = 15/1 * abc = 15abc

Answer 2

1.

$\frac{13}{24} d \times 32c = \frac{13 \times 32}{24} dc = \frac{ 13 \times 4 }{3} dc = \frac{52}{3} dc = 17 \frac{1}{3}dc$

2.

$6 \frac{3}{4} x \times 1 \frac{11}{45} y = \frac{27}{4} x \times \frac{56}{45} y = \frac{27 \times 56}{4 \times 45} xy = \frac{3 \times 14}{1 \times 5} xy = \frac{42}{5} xy = 8 \frac{2}{5} xy$

3.

$18 \frac{1}{3} a \times 1 \frac{2}{11} b \times \frac{9}{13} c = \frac{55}{3} a \times \frac{13}{11} b \times \frac{9}{13} c = \frac{55 \times 13 \times 9}{3 \times 11 \times 13} abc = \frac{5 \times 1 \times 3}{1 \times 1 \times 1} abc = 15abc$
