diketahui pecahan A = 31/124 dan B = 27/36 . bentuk desimal pecahan A dan B berturut turut.............. a. 0,25 dan 0,34. b. 0,25 dan 0,75. c. 0,4 dan

Pecahan A
31/124 => masing2 dibagi 31
= 1/4
= 0,25

Pecahan B
27/36 => masing2 dibagi 9
= 3/4
= 0,75
Jawaban : B

Please, let me answer your question :)
___________________________

[tex] \frac{31}{124} = \frac{31 \div 31}{124 \div 31} = \frac{1}{4} [/tex]

[tex] \frac{27}{36} = \frac{27 \div 9}{36 \div 9} = \frac{3}{4} [/tex]

Jika ke desimal :

[tex] \frac{1}{4} = \frac{1 \times 25}{4 \times 25} = \frac{25}{100} = 0.25[/tex]

[tex] \frac{3}{4} = \frac{3 \times 25}{4 \times 25} = \frac{75}{100} = 0.75 [/tex]

Jadi yg B jawabannya.
