$\huge\color{pink}{\mathfrak{ᴀɴsᴡᴇʀ}}$

lRatio of reading books to story books = 4:3

Number of reading books=24

Let the number of story books be x

$\sf 4 :3 = 24:x \\ \\ \sf \implies \frac{4}{3} = \frac{24}{x} \\ \\ \sf \implies4 \times x = 24 \times 3 \\ \\ \sf\implies4x = 72 \\ \\ \sf \implies \: x = \frac{72}{4} = 18$

So number of story books=18

Answer 2

Answer:

lRatio of reading books to story books = 4:3

Number of reading books=24

Let the number of story books be x

$: \implies4 \ratio3 = 24 : x \\ \\ \implies \frac{4}{3} = \frac{24}{x} \\ \\ \implies4 \times x = 24 \times 3 \\ (4 \times x = 4x)and(24 \times 3 = 72) \\ \\ \implies4x = 72 \\ \\ \implies \: x = \frac{72}{4} = 18$

So number of story books=18
