Kunci Jawaban Senang Belajar Matematika, Operasi Hitung Pecahan Halaman 4,5,7,8

Kerjakan penjulahan pecahan di bawah ini!

1. 4/5 + 3/4 = 16/20 + 15/20 = 31/20

2. 2/7 + 1/4 = 8/28 + 7/28 = 15/28

3. 2/5 + 5/8 = 16/40 + 25/40 = 41/40

4. 5/6 + 2/7 = 35/42 + 12/42 = 47/42

5. 5/7 + 4/9 = 45/63 + 28/63 = 73/69

Berikut kunci jawaban buku Matematika kurikulum 2013 kelas 5 halaman 7 tentang pengurangan pecahan.

Lengkapilah pecahan-pecahan senilai di bawah ini!

1. 4/5 – 1/4 = 16/20 – 5/20 = 11/20
2. 1/3 – 1/5 = 5/15 – 3/15 = 2/15
3. 3/5 – 1/3 = 9/15 – 5/15 = 4/15
4. 4/6 – 2/4 = 16/24 – 12/24 = 4/24
5. 5/6 – 4/5 = 25/30 – 24/30 = 1/30

Kerjakan pengurangan pecahan di bawah ini!

1. 7/8 – 3/4 = 14/16 – 12/16 = 2/16
2. 5/7 – 1/4 = 20/28 – 7/28 = 13/28
3. 3/4 – 5/9 = 27/36 – 20/36 = 7/36
4. 5/6 – 2/9 = 30/36 – 8/36 = 22/36
5. 6/7 – 5/8 = 48/56 – 35/56 = 13/56

Berikut kunci jawaban buku Matematika kurikulum 2013 kelas 5 halaman 8

1. 1/3 + 3/5 = 5/15 + 9/15 = 14/15 (M)
2. 2/3 + 3/4 = 8/12 + 9/12 = 17/12 (A)
3. 3/7 + 1/5 = 15/35 + 7/35 =22/35 (N)
4. 5/6 – 1/5 = 25/30 – 6/30 = 19/30 (D)
5. 5/7 – 1/4 = 20/28 – 7/28 = 13/28 (I)
6. 3/5 – 1/7 = 21/35 – 5/35 = 16/35 (R)
7. 5/8 – 1/6 = 15/24 – 4/24 = 11/24 (I)
