9/10 – 2/5 – 3/8 =.... tolong ya hasilnya berapa ,pake cara ya terima kasih

= 9/10 -2/5-3/8 (samakan penyebut)
= 36/40 - 16/40 - 15/40
= 20/40 - 15/40
= 5/40 (sederhanakan)
= 1/8

Mapel : Matematika
Bab : Pecahan

[tex] \frac{9}{10} - \frac{2}{5} - \frac{3}{8} \\ = \frac{4(9) - 8(2) - 5(3)}{40} \\ = \frac{36 - 16 - 15}{40} \\ = \frac{20 - 15}{40} \\ = \frac{5}{40} \\ = \frac{5 \div 5}{40 \div 5} \\ = \frac{1}{8} [/tex]

Maaf Kalau Salah
