1. Tentukan hasil pembagian pecahan berikut dalam bentuk pecahan yang paling sederhana!

3. Tentukan hasil berbagai bentuk pecahan ! Jawaban dalam bentuk desimal

$3.a. \frac{3}{4}:0,15 = \frac{3}{4}: \frac{15}{100}=\frac{3}{4} \times \frac{100}{15}=\frac{300}{60}=5$

$3.b. \frac{48}{100}:\frac{1}{5} = \frac{48}{100} \times \frac{5}{1}=\frac{240}{100}=2,4$

$3.c. \frac{476}{100}:\frac{7}{5} = \frac{476}{100} \times \frac{5}{7}=\frac{2380}{700}=\frac{340}{100}=3,4$

$3.d. \frac{65}{100}:\frac{125}{100} = \frac{65}{100} \times \frac{100}{125}=\frac{65}{125}=\frac{520}{1000}=0,52$

$3.e. 3\frac{1}{4}:0,5 = \frac{13}{4}: \frac{5}{10}=\frac{13}{4} \times \frac{10}{5}=\frac{130}{20}=6,5$

$3.f. 10,5 : 2\frac{1}{2} = \frac{105}{10}: \frac{5}{2}=\frac{105}{10} \times \frac{2}{5}=\frac{210}{50}=4,2$

$3.g. 2\frac{1}{5}: 0,4 = \frac{11}{5}: \frac{4}{10}=\frac{11}{5} \times \frac{4}{10}=\frac{110}{20}=5,5$

$3.h. 70% : 0,7= \frac{70}{100}: \frac{7}{10}=\frac{70}{100} \times \frac{10}{7}=\frac{700}{700}=1$

$3.i. 4,56 : \frac{4}{5}= \frac{456}{100}: \frac{4}{5}=\frac{456}{100} \times \frac{5}{4}=\frac{2280}{400}=5,7$
