Answer 2

$\boxed {\sf {\large {Understanding\ the\ question:}}}$

Here the concept of direct proportion is used, meaning that if one quantity increases, then the second quantity will also increase simultaneously. All the values given in direct proportion are equal, meaning that the simplest form of all the quantities is same.

Solution:

Here,

$\sf \dfrac {x_{1}}{y_{1}} = \dfrac {x_{2}}{y_{2}}$

$\sf \dfrac {1}{9} = \dfrac {3}{y_{2}}$

$\bigstar \sf {Cross\ multiplication}$

$\sf {y_{2} = 9 \times 3}$

$\bf \red {y_{2} = 27}$

____________________

$\sf \dfrac {x_{1}}{y_{1}} = \dfrac {x_{3}}{y_{3}}$

$\sf \dfrac {1}{9} = \dfrac {x_{3}}{45}$

$\bigstar \sf {Cross\ multiplication}$

$\sf {x_{3} = \dfrac {45}{9}}$

$\bf \pink {x_{3} = 5}$

____________________

$\sf \dfrac {x_{1}}{y_{1}} = \dfrac {x_{4}}{y_{4}}$

$\sf \dfrac {1}{9} = \dfrac {7}{y_{4}}$

$\bigstar \sf {Cross\ multiplication}$

$\sf {y_{4} = 7 \times 9}$

$\bf \green {y_{4} = 63}$
