tolong jawabin dong!!

Pembahasan :

Nilai m
[tex] = \frac{3}{8} \div \frac{3}{4} \\ = \frac{3}{8} \times \frac{4}{3} \\ = \frac{1}{2} [/tex]

Nilai n
[tex] = 2 \frac{1}{3} - 1 \frac{1}{7} \\ = \frac{7}{3} - \frac{8}{7} \\ = \frac{49 - 24}{21} = \frac{25}{21} [/tex]

Nilai m + nilai n
[tex] = \frac{1}{2} + \frac{25}{21} \\ = \frac{21 + 50}{42} = \frac{71}{42} = 1 \frac{29}{42} [/tex]
Opsi A

Good Luck ^^

Nilai : m = 3/8 : 3/4

              = 3/8 × 4/3

              = 1/2


Nilai : n = 2 1/3 - 1 1/7
     
             = 2 7/21 - 1 3/21

             = 1 4/21



dit : m + n

= 1/2 + 1 4/21

= 21/42 + 1 8/42

= 1 29/42  (a)



semoga membantu..........
