2. -85 : 17 =
3. -284 : (-71) =
4. 23 × 7 + 23 × (-6) =
5. -3 × (-20) + (-6) × (-20) =
1. -43 × (-16) =
1.) -43 × (-16)
= distribusikan menjadi = 43 × 16 = 688
maka hasil benarnya = -688
2.) -85 ÷ 17
= distribusikan menjadi = 85 ÷ 17 = 5
maka hasil benarnya = -5
3.) -284 ÷ (-71)
= distribusikan menjadi = 284 ÷ 71 = 4
maka hasil benarnya = -4
4.) 23 × 7 + 23 × (-6)
= distribusikan menjadi = 23 × 7 + (23 × -6)
= 161 + (23 × -6)
= 161 + (-138)
= 23
maka hasil benarnya = 23
5.) -3 × (-20) + (-6) × (-20) =
= (-3 × (-20)) + (-6) × (-20))
= 60 + 120
= 180
Jawaban:
1. -43 × (-16) = 688
2. -85 : 17 = 5
3. -284 : (-71) = 4
4. 23 × 7 + 23 × (-6)
= (23 × 7) + (23 × (-6))
= 161 + (-138)
= 23
5. -3 × (-20) + (-6) × (-20)
= (-3 × (-20)) + ((-6) × (-20))
= 60 + 120
= 180
