Answer:
5(3a ⋅ 4) = (5 ⋅ 3a) ⋅ 4
Step-by-step explanation:
The Associative Property is applied to two types of operations: addition and multiplication. This property indicates that, when there are three or more terms in these operations, the result does not depend on the way in which the terms are grouped.
In this sense, the associative property for the sum is mathematically given by:
and for the multiplication by:
Now, let:
Using the Associative Property of Multiplication:
Therefore the equivalent expressions are:
5(3a ⋅ 4) = (5 ⋅ 3a) ⋅ 4
n = 100 (or) 10²
Solution:
Given equation is 1.6 ÷ n = 0.016.
Part A:
To simplify the equation and find the value of n.
1.6 ÷ n = 0.016
Do cross multiplication.
Divide by 0.016 on both sides of the equation.
To remove decimal point multiply and divide by 1000 on left side.
Switch the sides.
n = 100
n = 10²
Hence the value of n is 10².
Part B:
= 0.016
Hence the answer is true.
