ayudaaaaaa productos de fracciones

1/8 x 2/3 x 2/9 = ?

3/7 x 2/9 x 1/8 = ?

4/7 x 5/6 x 9/5 = ?

1/9 x 3/11 x 4/7 = ?

Answer 1

$\frac{1}{8} . \frac{2}{3} . \frac{2}{9} = \frac{1.2.2}{8.3.9} = \frac{4}{216} = \frac{1}{54}$

$\frac{3}{7} . \frac{2}{9} . \frac{1}{8} = \frac{3.2.1}{7.9.8} = \frac{6}{504} = \frac{1}{84}$

$\frac{4}{7} . \frac{5}{6} . \frac{9}{5} = \frac{4.5.9}{7.6.5} = \frac{180}{210} = \frac{18}{21} = \frac{6}{7}$

$\frac{1}{9} . \frac{3}{11} . \frac{4}{7} = \frac{1.3.4}{9.11.7} = \frac{12}{693} = \frac{4}{231}$

Answer 2

Para multiplicar fracciones se multiplican los numeradores por los numeradores y los denominadores por los denominadores. Se simplifica si es necesario.

1. $\frac {1}{8} * \frac {2}{3} * \frac {2}{9} = \frac {1 * 2 * 2}{8 * 3 * 9}$ = $\frac {4}{216}$ = $\frac {2}{108}$ = $\frac {1}{54}$

Simplificado: 4/216
4 ÷ 2 = 2
216 ÷ 2 = 108

Simplificado: 2/108
2 ÷ 2 = 1
108 ÷ 2 = 54

2. $\frac {3}{7} * \frac {2}{9} * \frac {1}{8} = \frac {3 * 2 * 1}{7 * 9 * 8}$ = $\frac {6}{504}$ = $\frac {3}{252}$ = $\frac {1}{84}$

Simplificado: 6/504
6 ÷ 2 = 3
504 ÷ 2 = 252

Simplificado: 3/252
3 ÷ 3 = 1
252 ÷ 3 = 84

3. $\frac {4}{7} * \frac {5}{6} * \frac {9}{5} = \frac {4 * 5 * 9}{7 * 6 * 5}$=$\frac {180}{210}$=$\frac {90}{105}$ =$\frac {30}{35}$ =$\frac {6}{7}$

Simplificado: 180/210
180 ÷ 2 = 90
210 ÷ 2 = 105

Simplificado: 90/105
90 ÷ 3 = 30
105 ÷ 3 = 35

Simplificado: 30/35
30 ÷ 5 = 6
35 ÷ 5 = 7

4. $\frac {1}{9} * \frac {3}{11} * \frac {4}{7} = \frac {1 * 3 * 4}{9 * 11 * 7}$ = $\frac {12}{693}$ = $\frac {4}{231}$

Simplificado: 12/693
12 ÷ 3 = 4
693 ÷ 3 = 231
