Answer 2

$\qquad\huge\pink{\boxed{\sf Answer}}$

• 28 , x , 63
• 23 : x : x : 63

$\mathfrak\longmapsto ad \: = bc \:$

$\mathfrak\longmapsto 28 \times 63 = \times x \times$

$\mathfrak\longmapsto 2 \times 2 \times 7 \times 7 \times 3 \times 3 = \times x \times$

$\mathfrak\longmapsto 2 \times 7 \times 3 = x$

$\mathfrak\longmapsto 42 = x$

$\sf hence \: the \: proportional \: difference \: = \: 42$
