= (101x41/41041) + (101x42/42042) + (101x43/43043) + (101x44/44044) + (101x45/45045)
= 101/1001 + 101/1001 + 101/1001 + 101/1001 + 101/1001
= 505/1001
= 0.504495504
so, 4141/41041+4242/42042+4343/43043+4444/44044+4545/45045=0.504495504

= (101x41/41041) + (101x42/42042) + (101x43/43043) + (101x44/44044) + (101x45/45045)
= 101/1001 + 101/1001 + 101/1001 + 101/1001 + 101/1001
= 505/1001
= 0.504495504
