Answer 2

ANSWER-

Given,

• weight of 12 books = 48kg

Find,

• Weight of 56books=?
• Number books weighing 14kg =?

━━━━━━━━━━━━

$\huge{\bf{\underline{\red{SOLUTION}}}}$

12 books weigh 48kg

1book weigh $\frac{48}{12} kg \\ = 3kg$

Then, 56books will weigh

$56 \times 3kg \\ = 168kg$

━━━━━━━━━━━━

$\underline{\boxed{\pink{Weight\:of\:56\:books=\:168kg}}}$

━━━━━━━━━━━━

Now,

48 kg = 12 books

$1kg = \frac{12}{48} \\ 14kg = \frac{12}{48} \times 14 \\ => 14kg = \frac{14}{4} \\ => 14kg = 3.5$

━━━━━━━━━━━━━━

The number of books that will weigh 14kg is $\underline{\boxed{\pink{3\:and\:a\:half}}}$
