Tolong ya kak jawabannya ada di bawah tapi harus pake cara tolong kayak mana caranya ya?

Jawaban:

1. 0,6

2. 1,5

3. 3,5

4. 2,8

5. 0,4

6. 2,4

7. 0,3

1.) 0,5 x 1,2 = 0,6

[tex] \frac{5}{10} \times \frac{12}{10} = \frac{60}{100} = 0.6[/tex]

2.) 0,25 x 6 = 1,5

[tex] \frac{25}{100} \times 6 = \frac{150}{100} = 1.5[/tex]

3.) 2,5 x 1,4 = 3,5

[tex] \frac{25}{10} \times \frac{14}{10} = \frac{350}{100} = 3.5[/tex]

4.) 3,5 x 0,8 = 2,8

[tex] \frac{35}{10} \times \frac{8}{10} = \frac{280}{100} = 2.8[/tex]

5.) 0,6 : 1,5 = 0,4

[tex] \frac{6}{10} \div \frac{15}{10} = \frac{6}{10} \times \frac{10}{15} = \frac{60}{150} = \frac{2}{5} = \frac{4}{10} = 0.4[/tex]

6.) 3,6 : 1,5 = 2,4

[tex] \frac{36}{10} \div \frac{15}{10} = \frac{36}{10} \times \frac{10}{15} = \frac{360}{150} = \frac{12}{5} = \frac{24}{10} = 2.4[/tex]

7.) 2,0 : 2,4 = 0,8

[tex]2 \times \frac{10}{24} = \frac{20}{24} = 0.8[/tex]
