Question

Calcule as multiplicação
2-1/5 3-2/9 1/5-2/3 2/5-5/2 +10/7. 7/10 +8/5. 1/16.

Answer 1

Resposta:

Explicação passo a passo:

Calcule as multiplicação

= 2 - 1/5

= (5.2 - 1)/5

= (10-1)/5

= 9/5

_________

= 3 - 2/9

= (9.3 - 2)/9

= (27-2)/9

= 25/9

____________

= 1/5-2/3

Mmc (5,3)= 15

= (3.1 - 5.2)/15

= (3-10)/15

= - 7/15

_________

= 2/5 - 5/2 + 10/7. 7/10 +8/5. 1/16

= (2.2 - 5.5)/10 + 10/10.7/7 + 8/16.1/5

= (4 - 25)/10 + 1.1 + 8/80 (:8)/(:8)

= - 21/10 + 1 + 1/10

= - 20/10 + 1

= - 2 + 1

= - 1
