Examples 2 and 3 Evaluate each expression using properties of numbers. Name the property used in each step.

28.234鈰�118鈰�32

Short Answer

Expert verified

The value of expression is 99.

Step by step solution

01

– Write the formulae used

Associative property of multiplication:

a鈰�b鈰�c=a鈰�b鈰�c

Inverse property of multiplication:

a鈰�1a=1a鈰�a=1

Commutative property of multiplication:

a鈰�b=b鈰�a

02

– Write the given information 

The expression given is

234鈰�118鈰�32

03

- DESCRIPTION OF STEP 

To solve the given expression first simplify the mixed fraction(s) in the given expression as:

234鈰�118鈰�32=2脳4+34鈰�1脳8+18鈰�32=114鈰�98鈰�32

Now use the associative property to simplify the above expression further as:

114鈰�98鈰�32=114鈰�98鈰�32=114鈰�98鈰�8鈰�4=114鈰�9鈰�4=114鈰�4鈰�9commutativerule=11鈰�9=99

Thus,234鈰�118鈰�32=99
