yg aku linglati tolong jawab mohon pake cara pliss

7 . 25 / 100 x 23.000 = 5.750
= 23.000 - 5.750 = 17.250

maaf cmn bs jwb no 7 aja yg lainnya, soalny gk keliatan

5. 5 1/4 - 1/3 - 2 2/5 = 21/4 - 1/3 - 12/5 = 315/60 - 20/60 - 144/60 = 151/60 = 2 31/60 (B)
6. 6/7,4/6,1/3,3/21 (D)
7. 23.000 × 25% = 5.750
23.000 - 5.750 = 17.250 (A)
8. 16 = 2×8,2×4,2×2
28 = 2×14,2×7
42 = 2×21,3×7
KPK = 2^4×7×3 = 336 (D)
Maaf jika salah.
