Pak wiryo mempunyai pupuk 5 3_4 +4 3_5 dikurang 7 3_8=.... Sisa berapa pupuk yang belum digunakan??? pakai cara

5 3/4 + 4 3/5 - 7 3/8 = 23/4 + 23/5 - 59/8 = 230/40 + 184/40 - 295/40 = 119/40 = 2 39/40

good luck

[tex]5 \frac{3}{4} + 4 \frac{3}{5} - 7 \frac{3}{8} \\ = (5 + 4 - 7) + ( \frac{3}{4} + \frac{3}{5} - \frac{3}{8} ) \\ = (2) + ( \frac{120 + 96 - 60}{160} ) \\ = (2) + ( \frac{156}{160} ) \\ = 2 \frac{78}{80} = 2 \frac{39}{40} [/tex]
