Question

Calculati : [1 pe 10 +1 pe 19 ×(2 pe 3 +0,6 )]÷ 0,01

Answer 1

= [1/10 + 1/19 x ( 2/3+ 6/10) ] : 1/100 =

=> [1/10 + 1/19x( 20/30 + 18/30) ]:1/100 =

=> [ 1/10 + 1/19 x 38/30 ]: 1/100 =

=> [1/10 + 2/30 ] :1/100 =

= [3/30 + 2/30 ] :1/100 =

=> 5/30 :1/100 =

=> 1/6 : 1/100 =

=> 1/6 x 100 = 50/3 = 16,(6)

Answer 2

$( \frac{1}{10} + \frac{1}{19} \times ( \frac{2}{3} + 0.6) \div 0.01 \\ ( \frac{1}{10} + \frac{1}{19} \times \frac{2}{3} + \frac{3}{5} ) \div \frac{1}{100} \\ ( \frac{1}{10} + \frac{1}{19} \times \frac{19}{15} ) \times 100 \\ ( \frac{1}{10} + \frac{1}{15} ) \times 100 \div \frac{1}{6} \times 100 \\ \frac{1}{3} \times \frac{50}{1} \\ \frac{50}{1}$
