Answer 1

Răspuns:

4,(629)=(4619-4)/999=4625/999

0,41(6)=(9416-41)/900=375/900=5/12

4625/999:[(36-11)/9]-5/12=x/24

4625/999:25/9-5/12=x/24

4625/999·9/25-5/12=x/24 simplifici mezii cu extremii

185/111-5/12=x/24  aducem la acelasi numitor

2220/1332-555/1332=x/24

1665/1332=x/24

1332x=1665·24

x=39960:1332

x=30

Answer 2

Răspuns:

Explicație pas cu pas:

4,(629) = 4625/999

4 - 11/9 = 36/9 - 11/9 = 25/9

0.41(6) = (416 - 410/900 = 375/900 = 15/36 = 5/12

4625/999 : 25/9 = 4625/999 * 9/25 = 185/111

185/111 - 5/12 = 2220/1332 - 555/1332 = 1665/1332

1665/1332 = x/24

x = 24*1665/1332 = 2*1665/111 = 3330/111 = 30
