Question

Represente , sob a forma de fração irredutivel , cada das taxas percentuais :a ) 34%  b)3% c)315% d )0.8%

Answer 1

Oie, Td Bom?!

a) = 34%

= 34/100

= 34÷2/100÷2

= 17/50

b) = 3%

= 3/100

c) = 315%

= 315/100

= 315÷5/100÷5

= 63/20

d) = 0,8%

= 0,8/100

= (4/5)/100

= 4/5 ÷ 100

= 4/5 × 1/100

= 4×1/5×100 ⇐ Simplifica por 4.

= 1/5×25

= 1/125
