Nomor 2 sama 3 aja pake Cara plis

1.
[tex]65 \frac{15}{21} + 67 \frac{17}{28} \\ = (65 + 67) + ( \frac{15}{21} + \frac{17}{28} ) \\ = 132 + ( \frac{4(15) + 3(17)}{84} ) \\ = 132 + ( \frac{60 + 51}{84} )\\ = 132 + ( \frac{111}{84} ) \\ = 132 + (1 \frac{9}{28} ) \\ = 133 \frac{9}{28} [/tex]


2.
[tex]527 - \frac{7}{15} \\ = \frac{15(527) - 7}{15} \\ = \frac{7.905 - 7}{15} \\ = \frac{7898}{15} \\ = 526 \frac{8}{15} [/tex]
Maaf Kalau Salah
