Question

Cît va fi 1 întreg 1/4 × 8/15×5/9

Answer 1

$1 \frac{1}{4} \times \frac{8}{15} \times \frac{5}{9} =$

$\frac{1 \times 4 + 1}{4} \times \frac{8}{15} \times \frac{5}{9} =$

$\frac{5}{4} \times \frac{8}{15} \times \frac{5}{9} =$

$\frac{1}{1} \times \frac{2}{3} \times \frac{5}{9} =$

$1 \times \frac{2}{3} \times \frac{5}{9} =$

$\frac{2}{3} \times \frac{5}{9} =$

$\frac{2 \times 5}{3 \times 9} =$

$= \frac{10}{27}$
