Question

$\frac{5}{4} - \frac{4}{3} \times \frac{12}{5}$
​

Answer 1

Explicação passo-a-passo:

$\frac{5}{4} - \frac{4}{3} \times \frac{12}{5}$

$\frac{5}{4} - \frac{4 \times 12}{3 \times 5}$

$\frac{5}{4} - \frac{48}{15}$

mmc(4,15) = 60

$\frac{60 \div 4 \times 5}{60} - \frac{60 \div 15 \times 48}{60}$

$\frac{75}{60} - \frac{192}{60}$

$\frac{75 - 192}{60}$

$- \frac{117}{60}$

Simplificar por 3

$- \frac{117 \div 3}{60 \div 3}$

$= - \frac{39}{20}$
