Use algebra for 5.235235235... and 3.9999999... ???? , trying to interpret what that means
taking a stab:
let x = 5.235235235... , I see 3 digits repeating, so I will multiply by 1000
1000x = 5235.235235..
subtract them:
999x = 5230
x = 5230/999 , check with your calculator, it will be correct
do the other decimal in the same way, note that only ONE digit repeats, so what would you multiply by ?
Don't be surprised by the unexpected result.
Use algebra for 5.235235235... and 3.9999999... Also write these numbers as a fraction not a mixed number. How do I do this?
