Jawab:

1. 2 [tex]\frac{31}{60}[/tex]

2. 4,858

3. 2 [tex]\frac{13}{15}[/tex]

4. 38 [tex]\frac{1}{5}[/tex]

Penjelasan dengan langkah-langkah:

1.

= 5 [tex]\frac{1}{4}[/tex] - [tex]\frac{1}{3}[/tex] - 2 [tex]\frac{2}{5}[/tex]

= [tex]\frac{21}{4}[/tex] -  [tex]\frac{1}{3}[/tex] - [tex]\frac{12}{5}[/tex]

= [tex]\frac{315}{60}[/tex] - [tex]\frac{20}{60}[/tex] - [tex]\frac{144}{60}[/tex]

= [tex]\frac{479}{60}[/tex]

= [tex]\frac{151}{60}[/tex]

= 2 [tex]\frac{31}{60}[/tex]

2.

= 2,331 + 1,777 + 9/20 + 30%

= 2,331 + 1,777 + 0,45 + 0.3

= 4,858

3.

= 220% + 2/3

= 2 [tex]\frac{1}{5}[/tex] + [tex]\frac{2}{3}[/tex]

= [tex]\frac{11}{5}[/tex] + [tex]\frac{2}{3}[/tex]

= [tex]\frac{33}{15}[/tex] + [tex]\frac{10}{15}[/tex]

= [tex]\frac{43}{15}[/tex]

= 2 [tex]\frac{13}{15}[/tex]

4.

= 12,65 + 4,71 + 1/35

= 12 [tex]\frac{65}{100}[/tex] + [tex]\frac{71}{100}[/tex] + [tex]\frac{1}{35}[/tex]

=  [tex]\frac{1.265}{100}[/tex] + [tex]\frac{71}{100}[/tex] + [tex]\frac{1}{35}[/tex]

= [tex]\frac{25.300}{700}[/tex] + [tex]\frac{1.420}{700}[/tex] + [tex]\frac{20}{700}[/tex]

= [tex]\frac{26.740}{700}[/tex]

= 38 [tex]\frac{140}{700}[/tex]

= 38 [tex]\frac{1}{5}[/tex]
