com o cálculo prffv​

Answer 1

Explicação passo-a-passo:

.

.

.

$\dfrac{16}{3} - \dfrac{16}{4}$

$\dfrac{16}{3} - 4$

$\dfrac{16 - 12}{3}$

$\dfrac{4}{3}$

.

.

.

$\dfrac{3}{10} + \dfrac{2}{5} + \dfrac{1}{2} - \dfrac{1}{3}$

$\dfrac{9 + 12 + 15 - 10}{30}$

$\dfrac{26 \div 2}{30 \div 2}$

$\dfrac{13}{15}$

.

.

.

$\dfrac{3}{11} + \dfrac{8}{7}$

$\dfrac{21 + 88}{77}$

$\dfrac{109}{77}$

.

.

.

$\dfrac{1}{2} - \dfrac{1}{4} - \dfrac{1}{8}$

$\dfrac{4 - 2 - 1}{8}$

$\dfrac{1}{8}$
