1.2+7d

Practice makes perfect

Consider the given expression. 1.1+(7d+0.1) We are asked to simplify this expression. We can use the Properties of Real Numbers in order to do so. Let's do it!

Property/Operation Before After
Commutative Property of Addition 1.1+( 7d+ 0.1) 1.1+( 0.1+ 7d)
Associative Property of Addition 1.1+ (0.1+7d ) (1.1+0.1 )+7d
Add Terms ( 1.1+0.1)+7d 1.2+7d

Since 1.2 and 7d are not like terms, we cannot simplify further.
