Question

Explain how you might use the properties of multiplication to solve 5 × 120 × 6.232 mentally. Then solve.

Answer 1

Follows are the solution to this question:

Explanation:

In this question, we apply the associative property that calculates the given value, which can be defined as follows:

Rule:

`\bold{\to (A* B)* C= A * (B* C)}`

Let,

`A= 5\\B=120\\C=6.232`

put the value in the above rule:

Solve L.H.S part:

`\to (5* 120)* 6.232\\\\\to (600)* 6.232\\\\\to 3,739.2`

Solve R.H.S part:

`\to 5 * (120 * 6.232)\\\\\to 5 * 747.84\\\\\to 3,739.2`

So, L.H.S=R.H.S
