Jawab dengan benar dan lengkap!!! ....!!!!!! nomer 3-4 pecahan yg sederhana!!! 1)5 per 7 × 4 /3 = 2)5 4 /9 × 3 3 / 5= 3)3 4 / 3 × 2 2 / 3 = 4)1 1/11 × 7 2/6= 5)

1. [tex]\frac{5}{7}[/tex] x [tex]\frac{4}{3}[/tex] = [tex]\frac{20}{21}[/tex]

2. [tex]5\frac{4}{9}[/tex] x [tex]3\frac{3}{5}[/tex] = [tex]\frac{49}{9}[/tex] x [tex]\frac{18}{5}[/tex] = [tex]\frac{882}{45}[/tex] = [tex]19\frac{27}{45}[/tex] = [tex]19\frac{3}{5}[/tex]

3. [tex]3\frac{4}{3}[/tex] x [tex]2\frac{2}{3}[/tex] = [tex]\frac{13}{3}[/tex] x [tex]\frac{8}{3}[/tex] = [tex]\frac{104}{9}[/tex] = [tex]11\frac{5}{9}[/tex]

4. [tex]1\frac{1}{11}[/tex] x [tex]7\frac{2}{6}[/tex] = [tex]\frac{12}{11}[/tex] x [tex]\frac{44}{6}[/tex] = [tex]\frac{528}{66}[/tex] = 8

5. [tex]\frac{8}{12}[/tex] x [tex]\frac{5}{6}[/tex] = [tex]\frac{40}{72}[/tex] = [tex]\frac{5}{9}[/tex]

6. [tex]\frac{7}{5}[/tex] x [tex]\frac{3}{10}[/tex] = [tex]\frac{21}{50}[/tex]

7. [tex]\frac{9}{4}[/tex] x [tex]\frac{5}{20}[/tex] = [tex]\frac{45}{80}[/tex] = [tex]\frac{9}{16}[/tex]

8. [tex]\frac{6}{5}[/tex] x [tex]\frac{2}{15}[/tex] = [tex]\frac{12}{75}[/tex] = [tex]\frac{4}{25}[/tex]

1. 5/7 x 4/3 =20/21
2.5 4/9 x 3 3/5 = 49/9 x 18/5 ( 18 & 9 sama2 dibagi 9 ) = 98/5
3.3 4/3 x 2 2/3= 13/3 x 8/3 = 104/6
4.1 1/11 x 7 2/6 = 12/11 x 44/6 ( 12&6 sama2 dibagi 6) =88/11 menjadi 8
5.8/12 x 5/6 =40/72
6.7/5 x 3/10 = 21/50
7.9/4 x 5/20 = 45/80
8.6/5 x 2/15 =12/75
