kak tolonglah bantu aku........

1) Bilangan bulat
2) -9, -5, 3, 6
3) Asosiatif ( pengelompokkan)
4) 24 : 6 + 2 = 4 + 2 = 6
5) 700 = 2^2 x 5^2 x 7
6) 45/120, 100/120, 48/120, 90/120
Urutan dari yg besar = 100/120, 90/120, 48/120 dan 45/120
= 5/6, 3/4, 2/5, 3/8
7) 2 5/6 + 3 2/6 - 3/6 = 5 7/6 - 3/6 = 5 4/6 = 5 2/3
8) 9/8 × 2/27 × 3/4 = gunakan metode coret
= 1/8 × 1/1 × 1/2 = 1/16
9) uang Soni = (2 x 20rb) + 5rb + (2 × 1rb) = 47.000
Buku = 2 × 17.000 = 34.000
Sisa uang Soni = 47.000 - 34.000 = 13.000
10) Sisa kue = 1 - (1/4 + 1/8 + 1/2)
= 1 - (2/8 + 1/8 + 4/8)
= 1 - 7/8 = 8/8 - 7/8 = 1/8
