Answer 1

[3/10÷(7/4-2/5)]-7/20×4/14=0.12

[(7²-3²)÷8/5]×4/15-2/7×(4²-2)=3.999 946 461 671 61

6/5[1-2/7]÷7/9[81/21]+3/4.6/9=4.300 728 862 973 76

[8/3÷(6²-20)]×3/4(5²+1)=3.25

Answer 2

= 11/90

= 2⅔

= 11/14

= 3¼

Explicación paso a paso:

[(3/10) ÷ {(7/4) – (⅖)}] – (7/20) × (4/14)

= [(3/10) ÷ (27/20)] – (1/10)

= [(3/10) × (20/27)] – (1/10)

= (2/9) – (1/10)

= 11/90

[(7² – 3²) ÷ (8/5)] × (4/15) – (2/7) × (4² – 2)

= [(49 – 9) ÷ (8/5)] × (4/15) – (2/7) × (16 –2)

= [40 × ⅝] × (4/15) – (2/7) × 14

= 25 × (4/15) – 4

= (20/3) – 4

= 8/3 = 2⅔

(6/5) [1 – (2/7)] ÷ (7/9)(81/21) + (¾)(6/9)

= (6/5) [5/7] ÷ 3 + ½

= (6/7) × (1/3) + ½

= 2/7 + ½

= 11/14

[(8/3) ÷ (6² – 20)] × ¾(5² + 1)

= (8/3) ÷ 16 × ¾(26)

= (8/3) × (1/16) × (39/2)

= 13/4 = 3¼

¡Muchos éxitos!
