Answer 1

Answer:

$\frac{20}{3} is \: in \: year \: but \: not \: in \: perfect \: year \\ so \: we \: have \: to \: change \: in \: \\ year \: and \: month \\ \\ so \: at \: first \: we \: have \: to \: multiply \: \\ (see \: in \: 1st \: attachment \: for \: clear \\ understanding) \\ (1 \: year = 12 \: months ) \\ \frac{20}{3} \times 12 \\ 20 \times 4 \\ 80 \: months \\ \\ now \: we \: have \: to \: divide \: \\ 80 \div 12 \\ (see \: in \: 2nd \: attachment \: for \: this)$

$i \: hope \: now \: you \: understand \: \\ how \: \frac{20}{3} is \: written \: as \: 6 \: years \: 8 \: months$
