Question

5/3-3/16 x 1/2 + 7/11 : 32/11

Answer 1

5 / 3 - 3 / 16 x 1 / 2 + 7 / 11 x 11 / 32 =

= 5 / 3 - 3 / 32 + 7 / 32 =

→ cmmmc al numitorilor 3 si 32 este 96

→ amplific fractiile cu 32 si respectiv cu 3

= 160 / 96 - 9 / 96 + 21 / 96 =

= 172 / 96 =→ simplific prin 4

= 43 / 24 =

= 1 intreg si 19 / 24

sau mai simplu:  

5 / 3 - 3 / 32 + 7 / 32 = 5 / 3 + 4 / 32 = 5 / 3 + 1 / 8 =

= 40 / 24 + 3 / 24 =

= 43 / 24
