✍️ Jawab

4,5 - 8 2/5 =.....

[tex] = \frac{45}{10} - \frac{42}{5} [/tex]

[tex] = \frac{45 \div 5}{10 \div 5} - \frac{42}{5} [/tex]

[tex] = \frac{9 }{2} - \frac{42}{5} [/tex]

[tex] = \frac{9 \times 5}{10} - \frac{42 \times 2}{10} [/tex]

[tex] = \frac{45}{10} - \frac{84}{10} [/tex]

[tex] = \frac{(45 - 84)}{10} [/tex]

[tex] = \frac{ - 39}{10} [/tex]

[tex] = - 3 \frac{9}{10} [/tex]
