zysi [14]

Answer:

Follows are the solution to this question:

Step-by-step explanation:

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

Rule:

$\bold{\to (A\times B)\times C= A \times (B\times C)}$

Let,

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

put the value in the above rule:

Solve L.H.S part:

$\to (5\times 120)\times 6.232\\\\\to (600)\times 6.232\\\\\to 3,739.2$

Solve R.H.S part:

$\to 5 \times (120 \times 6.232)\\\\\to 5 \times 747.84\\\\\to 3,739.2$

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