Question

yg jawab duluan nanti dapet nilai gede​

Answer 1

Penjelasan dengan langkah-langkah:

1. Ubah ke desimal

a. 5/12 = 0,416

1/3 = 0,333

4/7 = 0,571

9/11 = 0,818

jadi urutan dari yg terkecil = 1/3,5/12,4/7,9/11

b. 2/5 = 0,4

1/2 = 0,5

7/9 = 0,777

5/13 = 0,384

jadi urutan dari yg terkecil = 5/13, 2/5, 1/2, 7/9

c. 1/2 = 0,5

7/3 = 2,333

3/7 = 0,428

7/11 = 0,636

jadi urutan dari yg terkecil = 3/7, 1/2, 7/11, 7/3

d. 5/3 = 1,666

1/13 = 0,076

9/7 = 1,285

12/13 = 0,923

jadi urutan dari yg terkecil = 1/13, 12/13, 9/7, 5/3

2. Sederhanakan

[tex]a. \: \frac{32}{11} = 2 \frac{10}{11} \\ b. \: \frac{12}{5} = 2 \frac{2}{5} \\ c. \: \frac{26}{40} = \frac{13}{20} \\[/tex]

[tex]d. \: \frac{15}{64}[/tex]

3. Desimal

a. 2/7 = 0,285

b. 22/10 = 2,2

[tex]c. \: 2 \frac{3}{4} = \frac{11}{4} = 2,75[/tex]

[tex]d. \:14 \frac{5}{6} = \frac{89}{6} = 14,83[/tex]

4. Persen ke pecahan biasa

a. 30% = 30/100 = 3/10

b. 12% = 12/100 = 3/25

c. 55% = 55/100 = 11/20

d. 78% = 78/100 = 39/50

5. Ubah ke permil

[tex]a. \: \frac{19}{20} = \frac{950}{1.000} = 950 \: ‰[/tex]

[tex]b. \: \frac{4}{5} = \frac{800}{1.000} = 800 \: ‰[/tex]

[tex]c. \: \frac{39}{125} = \frac{312}{1.000} = 312 \: ‰[/tex]

[tex]d. \: \frac{7}{8} = \frac{875}{1.000} = 875 \: ‰[/tex]
