Question

Plz answer these four math questions I'll give u a brainliest if u want...!!!




1. How could this be rewritten using only the associative property of multiplication?


(12 x 3) x 5 =



2. How could this be rewritten using only the associative property of multiplication?


(10 x 3) x 7 =



3. What property is being used in the following equation?


2 x 3 x 5 = 5 x 2 x 3



4. What property is being used in the following equation?


4 x 3 x 6 = 6 x 3 x 4

Answer 1

A U ( B U C ) =( A U B ) U C
it's the associate property
her how you change

Answer 2

ANSWER




QUESTION 1



How could this be rewritten using only the associative property of multiplication?

(12 x 3) x 5 =



Associative property .

a×(b×c)=(a×b)×c


Solution.



(12×3)×5=12×(3×5)



verification.


(12×3)×5=12×(3×5)


 2 x (15) and = 6 x (5)


= 30 = 30 


This means that 2 x (3 x 5) = (2 x 3) x 5 is right statement







QUESTION 2

2. How could this be rewritten using only the associative property of multiplication?

(10 x 3) x 7 =



SOLUTION.


(10 x 3) x 7 =10×(3×7)

30×7=10×21


210=210

This means that (10 x 3) x 7 =10×(3×7) is a right statement.







Question.3


4. What property is being used in the following equation?

4 x 3 x 6 = 6 x 3 x 4


Associate properties of mutiplcation numbers

and commutative property



REASON



a×(b×c)=(a×b)×c


so 4 x 3 x 6


(4×3)×6

=> using commutative property

(a×b)=(b×a)


=(3×4)×6


using associative property


= 3×(4×6)

=3×(6×4)


=(6×3)×4


=(3×6)×4


Using associative property


=( 6×3)×4

= 6×3×4
