tolong bantu saya yang bantu saya semoga mendapat kan pahala

1. 60%, 0,75, [tex] \frac{3}{4} , \frac{6}{8} , \frac{4}{5} [/tex]

2. 3600 detik = 60 menit = 1 jam.
total = [tex] \frac{3}{4} + \frac{1}{4} + 1 = 2 jam[/tex]

3. Bagas = a
Rido = b
Randi = c

[tex]a = \frac{3}{4} b[/tex]
[tex]b = \frac{5}{6} c [/tex]
[tex]a = \frac{3}{4} . \frac{5}{6} c = \frac{5}{8} c[/tex]

a + b + c = 59tahun
[tex] \frac{5}{8} c + \frac{5}{6} c + c = 59[/tex]
[tex] \frac{59}{24} c = 59[/tex]
[tex]c = 59 * \frac{24}{59} = 24[/tex]

[tex]a = \frac{5}{8} c = \frac{5}{8} . 24 = 15[/tex]

[tex]b = \frac{5}{6} c = \frac{5}{6}.24 = 20[/tex]

4. Beni = [tex] \frac{4}{3} [/tex] Rio
Beni = [tex] \frac{4}{3} [/tex] 9
Beni = 12

Edi = [tex] \frac{5}{3} [/tex] Rio
Edi = [tex] \frac{5}{3} [/tex] 9
Edi = 15

5. LΔ = [tex] \frac{1}{2} . a . t[/tex]
[tex]2.016 m^{2} = \frac{1}{2} . 42 . t[/tex]
t = 96m = 9600cm

skala 1 : 600
[tex] \frac{1}{600} = \frac{x}{9600} [/tex]
[tex] \frac{9600}{600} = x[/tex]
[tex]16 = x[/tex]
