kasih caranya yaaaaaa
Nomor a
[tex] \frac{3}{4} \div 0.15 \\ \\ = \frac{3}{4} \div \frac{15}{100} \\ \\ = \frac{ \not3}{ \not4} \times \frac{ \cancel{100} { \: }^{25} }{ \cancel{15} { \: }^{5} } \\ \\ = \frac{25}{5} \\ \\ = 5[/tex]
[tex] \\ [/tex]
Nomor b
[tex]0.48 \div \frac{1}{5} \\ \\ = \frac{48 \div 4}{100 \div 4} \div \frac{1}{5} \\ \\ = \frac{12}{25} \div \frac{1}{5} \\ \\ = \frac{12}{ \cancel{25} { \: }^{5} } \times \frac{ \not5}{1} \\ \\ = \frac{12}{5} \\ \\ = 2.4[/tex]
[tex] \\ [/tex]
Nomor c
[tex]4.76 \div 1 \frac{2}{5} \\ \\ = \frac{476 \div 4}{100 \div 4} \div \frac{7}{5} \\ \\ = \frac{119}{25} \div \frac{7}{5} \\ \\ = \frac{ \cancel{119} { \: }^{17} }{ \cancel{25} { \: }^{5} } \times \frac{ \not5}{ \not7} \\ \\ = \frac{17}{5} \\ \\ = 3.4[/tex]
[tex] \\ [/tex]
Nomor d
[tex]65\% \div 1.25 \\ \\ = \frac{65}{100} \div \frac{125}{100} \\ \\ = \frac{65}{ \cancel{100}} \times \frac{ \cancel{100}}{125} \\ \\ = \frac{65 \div 5}{125 \div 5} \\ \\ = \frac{13}{25} [/tex]
[tex] \\ [/tex]
Nomor e
[tex]3 \frac{1}{4} \div 0.5 \\ \\ = \frac{13}{4} \div \frac{5}{10} \\ \\ = \frac{13}{4} \times \frac{10}{5} \\ \\ = \frac{13}{ \bcancel4 {}^{2} } \times \not2 \\ \\ = \frac{13}{2} \\ \\ = 6.5[/tex]
[tex] \\ [/tex]
Nomor f
[tex]10.5 \div 2 \frac{1}{2} \\ \\ = \frac{105}{10} \div \frac{5}{2} \\ \\ = \frac{ \cancel{105} { \: }^{21} }{ \cancel{10} { \: }^{5} } \times \frac{ \not2}{ \not5} \\ \\ = \frac{21}{5} \\ \\ = 4.2[/tex]
[tex] \\ [/tex]
Nomor g
[tex]2 \frac{1}{5} \div 0.4 \\ \\ = \frac{11}{5} \div \frac{4 \div 2}{10 \div 2} \\ \\ = \frac{11}{5} \div \frac{2}{5} \\ \\ = \frac{11}{ \not5} \times \frac{ \not5}{2} \\ \\ = \frac{11}{2} \\ \\ = 5.5[/tex]
[tex] \\ [/tex]
Nomor h
[tex]70\% \div 0.7 \\ \\ = \frac{70}{100} \div \frac{7}{10} \\ \\ = \frac{ \cancel{70} { \: }^{ \cancel{10}} }{ \cancel{100}} \times \frac{ \cancel{10}}{ \not7} \\ \\ = 1[/tex]
[tex] \\ [/tex]
Nomor i
[tex]4.56 \div \frac{4}{5} \\ \\ = \frac{456 \div 4}{100 \div 4} \div \frac{4}{5} \\ \\ = \frac{114}{25} \div \frac{4}{5} \\ \\ = \frac{ \cancel{114} { \: }^{36} }{ \cancel{25} { \: }^{5} } \times \frac{ \not5}{ \not4} \\ \\ = \frac{36}{5} \\ \\ = 7.2[/tex]
Jawaban:
a. 3/4 :0,15= 0,75 : 0,15 = 5
b. 0,48: 1/5= 0,48 : 0,2 = 2,4
c. 4,76 : 1 2/5 = 4,75 : 1,4 = 3,392
d. 65%:1,25= 0,65 : 1,25 = 0,52
e. 3 1/4 :0,5= 3,25 : 0,5 = 6,5
f. 10,5: 2 1/2= 10,5 : 2,5 = 4,2
g. 2 1/5 :04= 2,2 : 0,4 = 5,5
h. 70%:0,7= 0,7 : 0,7 = 1
i. 4,56: 4/5= 4,56 : 0,8 = 5,7
semoga membantu
