1. Hasil dr 5/6 +1/4 ialah
2. hasil dr 3/7 + 2/5 yaitu
3. Hasil dr 5/8 + 7/16 + 3/4 adalah
4. hasil dr 5/8 + 3/4 + 5/6 yakni
Penjelasan dgn langkah-langkah:
[tex]1). \: \: \: \frac 5 6 + \frac 1 4 = \frac 10 + 3 12 = \frac 13 12 = 1 \frac 1 12 [/tex]
[tex]2). \: \: \: \frac 3 7 + \frac 2 5 = \frac 15 + 14 35 = \frac 29 35 [/tex]
[tex]3). \: \: \: \: \frac 5 8 + \frac 7 16 + \frac 3 4 = \frac 10 + 7 + 12 16 = \frac 29 16 = 1 \frac 13 16 [/tex]
[tex]4). \: \: \: \frac 5 8 + \frac 3 4 + \frac 5 6 = \frac 15 + 18 + 20 24 = \frac 53 24 = 2 \frac 5 4 [/tex]
Hasil dr 3/5 + 7/4 =….. . Hasil dr 4 2/6 + 1/4 =…. Hasil dr 5 2/3 + 3 1/2 =….. Hasil dr 2 3/2 + 5/8 = Hasil dr 4 2/3 + 3 2/5 =…. 1/3 + 6/7 = .2/3 + 4/9 = 5/16 + 7/8 = 7/8 + 6/7 = 5/9 + ¾ = 1/5 + 8/13 =
Jawaban:
[tex] \frac 3 5 + \frac 7 4 = \frac 12 20 + \frac 35 20 = \frac 47 20 \\ 4 \frac 2 6 + \frac 5 8 = \frac 18 24 + \frac 15 24 = \frac 32 24 \\ 5 \frac 2 3 + 3 \frac 1 2 = \frac 20 6 + \frac 10 6 = 10[/tex]
Tentukan hasil dr 3/5+4/5= 7/8+3/4= 4/10+5/8= 6/7+3/7= 5/6+4/12=
Jawaban:
maaf kalau salah…..
Penjelasan dgn tindakan:
hasil dr 4/5 + 5/6, 7/8 + 3 1/4, 4/5 + 3/2. 7/8 – 5/6
4/5 + 5/6 = 4×6/5×6 + 5×5/6×5
= 24/30 + 25/30 = 49/30
3 1/4 = 13/4
7/8 + 13/4 = 7×4/8×4 + 13×8/4×8
= 28/32 + 104/32 = 132/32
4/5 + 3/2 = 4×2/5×2 + 3×5/2×5
= 8/10 + 15/10 = 23/10
7/8 – 5/6 = 7×6/8×6 – 5×8/6×8
= 42/48 – 40/48 = 42-40/48 = 2/48
