Question

Semplifique as frações.

A) 36 =
72


B) 25 =
100​

Answer 1

$a) \frac{36( \div 2)}{72( \div 2)} =$

$\frac{18( \div 2)}{36( \div 2)} =$

$\frac{9( \div 3)}{18( \div 3)} =$

$\frac{3( \div 3)}{9( \div 3)} = \frac{1}{3}$

$b) \frac{25( \div 5)}{100( \div 5)} =$

$\frac{5( \div 5)}{20( \div 5)} = \frac{1}{4}$
