Answer 2

Concept:

The unitary approach or method is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.

An arithmetic value used to compute and represent a quantity is called a number.

Given:

A big pack has 12 packets of crisps. We buy n big packets of crisps.

Find:

The total number of crisps bought.

Solution:

There are 12 packets of crisps in a big packet.

The total number of n big packs are bought.

Using the unitary method,

1 big pack = 12 packets of crisps

n big packs of crisps = 12 x n of crisps = 12n packets of crisps.

Therefore, the total number of packets of crisps bought is 12n.
