tolong jawab plisss........kak.......no 3 sama 4

3. 10/7 , 7/6 , 3/5
samakan penyebut = KPK
7 = FP = 7
6 = FP = 2×3
5 = FP = 5
KPK = 7×2×3×5 = 210
210 ÷ 7 = 30 = 10/7 × 30/ 30 = 300/210
210 ÷ 6 = 35 = 7/6 × 35/35 = 245/210
210 ÷ 5 = 42 = 3/5 × 42/42 = 126/210
Jawab : 10/7 , 7/6 , 3/5

4. 12/8 , 13/10 , 14/6 , 15/5
samakan penyebut = KPK
8 = FP = 2×2×2
10 = FP = 2×5
6 = FP = 2×3
5 = FP = 5
KPK = 2×2×2×3×5 = 120
8 ÷ 120 = 15 = 12/8 × 15/15 = 180/120
10 ÷ 120 = 12 = 13/10 × 15/15 = 195/120
6 ÷ 120 = 20 = 14/6 × 20/20 = 280/120
5 ÷120 = 24 = 15/5 × 24/24 = 360/120

Jawab : 15/5 , 14/6 , 13/10 , 12/8
