Question

Resolva as expressões acima

Answer 1

a) √47/4 : 7/16 - 4/3 =

7/4 : 7/16 - 4/3 =

7/4 . 16/7 - 4/3 =

112/28 - 4/3 =

4 - 4/3 =          mmc(1,3) = 3

3.4/3 - 1.4/3 =

12/3 - 4/3 =

8/3

√16/5 - 7/15 + 1/25 =

4/5 - 7/15 + 1/25 =           mmc(5,15,25) = 75

15.4/75 - 5.7/75 + 3.1/75 =

60/75 - 35/75 + 3/75 =

28/75

√121/4 : 11/16 + 4/5 =

11/4. 16/11 + 4/5 =

176/44 + 4/5 =         mmc(44, 5) = 220

5.176/220 + 44.4/220 =

880/220 + 176/220 =

1056/220 =        (simplificar ambos por 44)

24/5
