Answer 1

Respuesta:

Explicación paso a paso:

1.) 5 × 7/9 - 3 × 1/3 - 11/36 + 1/4

35/9 - 1 - 11/36 + 1/4

(140 - 36 - 11)/36 + 1/4 = 93/36 + 1/4 = (93 + 9)/36 = 102/36 = 34/12 = 17/6

2.)  90/51 × 41/108 × 34/82

simplificamos:

30/17 × 1/108 × 34/2

15/1 × 1/54 × 2/2 = 15/54 = 5/18

3.) (2/3  −  1/4) ∙ (2/3  +  3/4)

((8 - 3)/12) × ((8 + 9)/12)

5/12 × 17/12 = 85/144

4.) 81/97 ÷ 18

81/97 × 1/18 = 9/97 × 1/2 = 9/194

5.) (6 - 3/5 + 1/10) ÷ 5×1/2

((60 - 6 + 1)/10) ÷ 5×1/2

55/10 ÷ 5/2 = 55/10 × 2/5 = 11/5

6.)  4/41  +  7/82  −  1/6

(8 + 7)/82 - 1/6 = 15/82 - 1/6

(45 - 41)/82 = 4/141

7.) 8·2/5  × 2·4/7  ×  7·1/9 × 2·7/10

19911/5000

8.) 14/55  ÷  8/35

14/55 × 35/8 = 49/44
