tolong bantu jawab ya​

1. (-12)×(27+(-10))÷(21-28)=

Penjelasan dengan langkah-langkah:

1. (-12) × (27+(-10)) : (21-28)

` = (-12) × 17 : (-7)

` = (-204) : (-7)

` = 29,142857…..

` = 29,2

2. 21 × ((-29)+8) : ((-34)+20)

` = 21 × (-21) : (-14)

` = (-441) : (-14)

` = 31,5

3. (-12) × 9 + (-10) : ((-11)-21)

` = (-12) × 9 + (-10) : (-32)

` = ((-12)×9) + ((-10):(-32))

` = (-108) + 320

` = 212

Maaf semisal jawaban saya salah, dan semoga membantu. Terimakasih!
