Answer 1

Answer:

$\huge\mathfrak\purple{Answer}$

80 : x :: 30 : 24

⇛80 × 24 = 30x

⇛ 1,920 = 30x

⇛30x = 1,920

⇛ 30x/30 = 1,920/30

⇛ x = 64 [ans ]

Answer 2

$\huge\bold{\mathtt{\purple{ A{\pink{ N{\green{ S{\blue{ W{\red{ E{\orange{ R}}}}}}}}}}}}}$

80 : x :: 30 : 24

$\implies$80 × 24 = 30x

$\implies$ 1,920 = 30x

$\implies$30x = 1,920

$\implies$ 30x/30 = 1,920/30

$\implies$ x = 64
