tolong dijawab please, dengan caranya, jangan ngasal!
Penjelasan dengan langkah-langkah:
1. ( - 2,7 ) - ( - 3,4 ) = ( - 2,7 ) + 3,4
= 0,7
2. 1/5 - ( - 4/5 ) = 1/5 + 4/5
= 5/5
= 1
3. ( -¾ ) - ( -½ ) = ( - ¾ ) + ½
= ( - 9/12 ) + 6/12
= -3/12
= - 0,25
4. 1/6 - ¾ = 2/12 - 9/12
= -7/12
5. ( -2/7 ) + 6/7 - 3/7 = 1/7
6. ( -4/7 ) × ( 7/8 ) = - 28/56
= - 0,5
7. ⅔ × ( - 9/2 ) = - 18/6
= - 3
8. ( - 2,5 ) × ( - 4/3 ) = 3,33
9. ( - ⅓ ) : ¾ = 0,277
10. ( - 5/6 ) : ( - 3 ) = 0,277
