Morgan rewrote the expression 90 +(10 + 4.8) as (90 + 10) + 4.8. How will this change the work that is needed to evaluate the expression?
Answers
Answer:
Both expressions are same. the result is same.
Step-by-step explanation:
Associative property of addition
a + (b + c ) = (a + b) + c
It is given two expressions,
90 +(10 + 4.8) and (90 + 10) + 4.8
This two expression are same.
This expression are an example of associative property of addition
Therefore 90 +(10 + 4.8) and (90 + 10) + 4.8
Evaluate 90 +(10 + 4.8)
90 + (10 + 4. 8) = 90 + 14.8 = 104.8
Evaluate (90 + 10) + 4.8
(90 + 10) + 4.8 = 100 + 4.8 = 104.8
Answer:
The result is same as it is associative property but he has to solve the brackets first by BDMAS rule
Step-by-step explanation:
Associative property of addition gives us that
a + (b + c ) = (a + b) + c
It is given two expressions,
90 +(10 + 4.8) and (90 + 10) + 4.8
This two expression are same.
This expression are an example of associative property of addition
Now what he will be the change the result will always be the same
Bur in first case he has to evaluate 10 + 4.8 because it is in the brackets
and he has to follow the BDMAS rule
and in second he has to follow (90+10) first that the only change that will happen but result will be same
