Question

Calculati:
e) 5 supra 9 :1 supra 6
f) 2 supra 7 : 1 intreg, 1 supra 3
g) 5 intregi, 1 supra 2 : 4 supra 3
h) 5 intregi, 1 supra 2 : 10 intregi, 1 supra 4.​

Answer 1

$e) \frac{5}{9} \div \frac{1}{6} = \frac{5}{9} \times 6 = \frac{10}{3}$

$f) \frac{2}{7} \div 1 \frac{1}{3} = \frac{2}{7} \div \frac{1 \times 3 + 1}{3} = \\ = \frac{2}{7} \div \frac{4}{3} = \frac{2}{7} \times \frac{3}{4} = \frac{3}{14}$

$g)5\frac{1}{2} \div \frac{4}{3} = \frac{5 \times 2 + 1}{2} \times \frac{3}{4} = \frac{11}{2} \times \frac{3}{4} =$

$= \frac{33}{8}$

$h)5\frac{1}{2} \div 10 \frac{1}{4} = \frac{5 \times 2 + 1}{2} \div \frac{4 \times 10 + 1}{4} =$

$= \frac{11}{2} \times \frac{4}{41} =$

$= \frac{22}{41}$
