Jawaban:
- 25. 6 (A).
- 26. 2,5 (B).
- 27. 1 1/5 (C).
- 28. 2 3/4 (tidak di opsi)
- 30. 1/4 kg (A).
Penjelasan:
- Soal nomor 25.
- 8 - 2 4/5 : 1 2/5
- = 8 - (14/5 : 7/5)
- = 8 - (14/5 x 5/7)
- = 8 - 2
- = 6
- Soal nomor 26.
- (4 - 3 1/5) : 2/3 + 1,3
- = 4/5 : 2/3 + 1,3
- = (4/5 x 3/2) + 1,3
- = 6/3 + 1,3
- = 2,5
- Soal nomor 27.
- (1 - 13/20) : 1 3/4 + (1,2 - 1/5)
- = 7/20 : 7/4 + (1,2 - 0,2)
- = (7/20 x 4/7) + 1
- = 1/5 + 1
- = 1 1/5
- Soal nomor 28.
- (1 1/2 + 1,5) - 1/4
- = (3/2 + 3/2) - 1/4
- = 6/2 - 1/4 = 3 1/4
- = 2 3/4
- Soal nomor 30.
Sisa tepung = tepung ibu - tepung yang dipakai
- = 5 (0,5 kg) - 2 1/4 kg
- = 5 (1/2 kg) - 9/4 kg
- = 5/2 kg - 9/4 kg
- = (10/4 - 9/4) kg
- = 1/4 kg
