bantu dong, pake cara ​

Jawaban:

Nomor 1.

[tex] \frac{10}{20} - \frac{1}{5} [/tex]

[tex] = \frac{10 \: - \: 1 \times 4}{20} [/tex]

[tex] = \frac{10 \: - \: 4}{20} [/tex]

[tex] = \frac{6}{20} [/tex]

[tex] = \frac{3}{10} [/tex]

Nomor 2.

[tex] \frac{15}{50} - \frac{4}{20} [/tex]

[tex] = \frac{3}{10} - \frac{1}{5} [/tex]

[tex] = \frac{3 \: - \: 1 \times 2}{10} [/tex]

[tex] = \frac{3 \: - \: 2}{10} [/tex]

[tex] = \frac{1}{10} [/tex]

[tex] \: [/tex]

[ 1 ]

[tex] \sf \: \frac{10}{20} - \frac{1}{5} [/tex]

[tex] \sf \: = \frac{10}{20} - \frac{(1 \times 4)}{(5 \times 4)} [/tex]

[tex] \sf \: = \frac{10}{20} - \frac{4}{20} [/tex]

[tex] \sf \: = \frac{6}{20} [/tex]

[tex] \sf \: = \frac{( 6 \div 2)}{(20 \div 2)} [/tex]

[tex] \sf \: = \frac{3}{10} [/tex]

[ 2 ]

[tex] \sf \: \frac{15}{50} - \frac{4}{20} [/tex]

[tex] \sf \: = \frac{15 \div 5}{50 \div 5} - \frac{4 \div4 }{20 \div 4} [/tex]

[tex] \sf \: = \frac{3}{10} - \frac{1}{5} [/tex]

[tex] \sf \: = \frac{3}{10} - \frac{(1 \times 2)}{(5 \times 2)} [/tex]

[tex] \sf \: = \frac{3}{10} - \frac{2}{10} [/tex]

[tex] \sf \: = \frac{1}{10} [/tex]
