Jawab:
1) 1[tex]\frac{1}{2}[/tex] x 0,03 = [tex]\frac{3}{2}[/tex] x [tex]\frac{3}{100}[/tex]
= [tex]\frac{9}{200}[/tex]
= 0,045
2) 4[tex]\frac{2}{5}[/tex] x 0,13 = [tex]\frac{22}{5}[/tex] x [tex]\frac{13}{100}[/tex]
= [tex]\frac{286}{500}[/tex]
= 0,572
3) 3[tex]\frac{3}{8}[/tex] x 0,43 = [tex]\frac{27}{8}[/tex] x [tex]\frac{43}{100}[/tex]
= [tex]\frac{1161}{800}[/tex]
= 1,45
4) 0,125 x 5[tex]\frac{1}{2}[/tex] = 0,125 x [tex]\frac{11}{5}[/tex]
= 0,125 x 5,5
= 0,687
5) 1,75 x 6³/₁₀ = 1,75 x [tex]\frac{63}{10}[/tex]
= 1,75 x 6,3
= 11,025
6) 2[tex]\frac{7}{9}[/tex] x 27% = [tex]\frac{25}{9}[/tex] x [tex]\frac{27}{100}[/tex]
= [tex]\frac{27}{9}[/tex] x [tex]\frac{25}{100}[/tex]
= 3 x 0,25
= 0,75
7) 3[tex]\frac{3}{4}[/tex] x 25% = [tex]\frac{15}{4}[/tex] x [tex]\frac{25}{100}[/tex]
= [tex]\frac{375}{400}[/tex]
= 0,937
8) 2[tex]\frac{15}{25}[/tex] x 30% = [tex]\frac{65}{25}[/tex] x [tex]\frac{30}{100}[/tex]
= [tex]\frac{1950}{250}[/tex]
= 7[tex]\frac{200}{250}[/tex]
=[tex]7\frac{20}{25}[/tex]
= 7,8
9) 19% x 4[tex]\frac{5}{6}[/tex] = [tex]\frac{19}{100}[/tex] x [tex]\frac{29}{6}[/tex]
= [tex]\frac{551}{600}[/tex]
= 0,91
10) 45% x 3[tex]\frac{3}{8}[/tex] = [tex]\frac{45}{100}[/tex] x [tex]\frac{27}{8}[/tex]
= [tex]\frac{1215}{800}[/tex]
= 1,518
