3. Let Y stand for the 45-digit number made of fifteen 1s, then fifteen 2s, then fifteen 3s. Y=11111111111111122222222222222233 3333333 Consider the repeating decimal with Y starting right after the decimal point and repeating: 22223 1222222222 333311 1122222222222 3333.... (so it's .YYY... with Y repeating). Which of the following fractions would have this repeating decimal expression with repeater Y? a. Y/999....9 (there are 45 nines in the denominator) b. Y/999....9 (there are 46 nines in the denominator) c. Y/999....9 (there are 44 nines in the denominator) d. Y/945 e. Y/946 f. Y/944
