19/45 is 0.42222222 if you round that to the nearest thousandth you get 0.422.
Area=length x width
A=lw
A=12 3/8
l=x
w=2 3/4
first, make your mixed numbers into improper fractions
12 3/8 --> 99/8
2 3/4 --> 11/4
then, set equal denominators
99/8 and 22/8
99/8=22/8x --plug in values
99/22=x --divide both sides by 22/8
convert improper fraction to mixed number
99/22 --> 4 11/22 --> 4 1/2
therefore, the length is 4 1/2 meters
Answer:
It is Commutative
Step-by-step explanation:
An operation ∆ is said to be Commutative if a∆b=b∆a ∀ a,b ∈ ℝ.
Given the operation ∆ defined by:
a∆b=a X b

a∆b=
=3
Similarly, for the right hand side.

Therefore:
b∆a=
=3
These are the two ways of solving this problem and we have in fact shown that the operation is commutative as:
a∆b=b∆a=3
Solution A1 is correct hope it helpsss
