bonjour merci de bien vouloir m'aider fraction decimales 4/100=...../1000 8100/1000=..../10 20/100=2/..... 32/10=......./1000 400/100=.... 52/100=52000/...... m

Bonsoir,

4/100 = ( 4 × 10 ) / ( 100 × 10 ) = 40/1000

8100/1000 = ( 8100 ÷ 100 ) / ( 1000 ÷ 100 ) = 81/10

20/100 = ( 20 ÷ 10 ) / ( 100 ÷ 10 ) = 2/10

32/10 = ( 32 × 100 ) / ( 10 × 100 ) = 3200/1000

400/100 = ?

52/100 = ( 52 × 1000 ) / ( 100 × 1000 ) = 52000/100000

Bonne soirée !
