Jawaban:

8. A

9. C

10. D

Penjelasan dengan langkah-langkah:

$5 - frac{4}{7} = frac{35}{7} - frac{4}{7} = frac{31}{7} = 4 frac{3}{7}$

$6 frac{6}{7} - frac{1}{3} = frac{48}{7} - frac{1}{3} = frac{144}{21} - frac{7}{21} = frac{137}{21} = 6 frac{11}{21}$

10.

$2 frac{2}{4} - 1.5 = frac{10}{4} - frac{15}{10} = frac{50}{20} - frac{30}{20} = frac{20}{20} = 1$

Semoga membantu

Penjelasan dengan langkah-langkah:

8. 5 – 4/7

= 5/1 – 4/7

= {7:1×5} – {7:7×4}

= 35/7 – 4/7

= 31/7

= 4 3/7

= A

9.6 6/7 – 1/3

= 48/7 – 1/3

= {21:7×48} – {21:3×1}

= 144/21 – 7/21

= 137/21

= 6 11/21

= C

10. 2 2/4 – 1,5

= 10/4 – 15/10

= {20:4×10} – {20:10×15}

= 50/20 – 30/20

= 20/20

= A
