(2×10)+(3×1)+(7×110)+(5×1 over 100)
left parenthesis 2 times 10 right parenthesis plus left parenthesis 3 times 1 right parenthesis plus left parenthesis 7 times Start Fraction 1 over 10 End Fraction right parenthesis plus left parenthesis 5 times Start Fraction 1 over 100 End Fraction right parenthesis

(5×10)+(7×1)+(3×110)+(2×1 over 100)

Answer 1

so easy; why do you punt?
(2×10)+(3×1)+(7×1101)+(5×1/10^2) = 154601/20 = 7730 1/20
(2×10)+(3×1)+(5×110)+(7×1/100) = 57307/100 = 573 7/100
and so on

Answer 2

5 times 10 plus 7 times 1 plus 3 times 110 plus 2 times Start Fraction 1 over 100 End Fraction.

Answer 3

Apologies for any confusion. Yes, you are correct in your calculations.

(2×10)+(3×1)+(7×1101)+(5×1/10^2) = 154601/20 = 7730 1/20

(2×10)+(3×1)+(5×110)+(7×1/100) = 57307/100 = 573 7/100

Thank you for pointing that out.
