Question

Calculeaza:c)3pe4•8pe9-3pe4:6
d)0,23:2,3•10+1pe3

Answer 1

Raspuns:

$c) \frac{3}{4} \times \frac{8}{9} - \frac{ 3}{4} \div 6$

$\frac{2}{3} - \frac{3}{4} \times \frac{1}{6}$

$\frac{2}{3} - \frac{1}{4} \times \frac{1}{2}$

$\frac{2}{3} - \frac{1}{8}$

$\frac{13}{24}$

$d)0.23 \div 2.3 \times 10 + \frac{1}{3}$

$1 + \frac{1}{3}$

$\frac{4}{3}$
