Answer 1

Answer:

2kg

Step-by-step explanation:

Given:

Weight of 15 books = 6kg

To Find:

Weight of 5 books = ??

Solve:

$\mathtt{Weight \:of \:15 \:books = 6kg}$

$\mathtt{Weight \:of\: 1 \:book = \frac{6kg}{15}}$

$\mathtt{Weight \:of \:1 \:book = \frac{2}{5}}$

$\mathtt{Weight \:of\: 5 \:books = \frac{2}{5}\times5}$

$\mathtt{Weight\: of \:5 \:books = 2kg}$

Some Extra Information:

• In the ratio i : n, we call i antecedent (first term) and n consequent (second term).
• Numbers a, b, c, d are said to be in proportion, if a:b=c:d and we write it as a:b::c:d
