Answer 1

Jawaban:

Penyelesaian :

[tex] \sf \frac{2}{3} \times 0,25 + \frac{1}{5} \times 0,6[/tex]

[tex] \sf = \frac{2}{3} \times \frac{25}{100} + \frac{1}{5} \times \frac{6}{10} [/tex]

[tex] \sf = \frac{2}{3} \times \frac{ { \cancel{25}}^{ \: 1} }{ { \cancel{100}}^{ \: 4} } + \frac{1}{5} \times \frac{ { \cancel{6}}^{ \: 3} }{ { \cancel{10}}^{ \: 5} } [/tex]

[tex] \sf = \frac{2 }{3} \times \frac{1}{4} + \frac{1}{5} \times \frac{3}{5} [/tex]

[tex] \sf = \frac{2 \: \times \: 1 }{3 \: \times \: 4} + \frac{1 \: \times \: 3}{5 \: \times \: 5}[/tex]

[tex] \sf = \frac{2}{12} + \frac{3}{25} [/tex]

[tex] \sf = \frac{1}{6} + \frac{3}{25} [/tex]

[tex] \sf = \frac{1 \times 25}{150} + \frac{3 \times 6}{150} [/tex]

[tex] \sf = \frac{25}{150} + \frac{18}{300} [/tex]

[tex] \sf = \frac{43}{150} [/tex]

Answer 2

2/3 × 0,25 + 1/5 × 0,6

= 2/3 × 25/100 + 1/5 × 6/10

= 2/3 × 1/4 + 1/5 × 3/5

= (2(1)/(3(4) + (1(3)/(5(5)

= 2/12 + 3/25

= 1/6 + 3/25

= 25/150 + 18/150

= 43/150
