Lloyd is practising his arithmetic by taking the reciprocal of a number and by adding 1 to a number. Taking the reciprocal of a number is denoted by →R\xrightarrow{R} and adding 1 is denoted by →A\xrightarrow{A}. Here is an example of Lloyd's work, starting with an input of 2: 2→R12→A32→R23→A53→R352 \xrightarrow{R} \frac{1}{2} \xrightarrow{A} \frac{3}{2} \xrightarrow{R} \frac{2}{3} \xrightarrow{A} \frac{5}{3} \xrightarrow{R} \frac{3}{5} (a) Using an input of 3, fill in the five blanks below: 3→R___→A___→R___→A___→R___3 \xrightarrow{R} \_\_\_ \xrightarrow{A} \_\_\_ \xrightarrow{R} \_\_\_ \xrightarrow{A} \_\_\_ \xrightarrow{R} \_\_\_
