Answer:
The correct option is (D).
Step-by-step explanation:
The two expressions are:
On simplifying both the expressions we get:
Compute the value of both expressions for <em>x</em> = 2 as follows:
The value of both expressions are same for <em>x</em> = 2.
Thus, the correct option is:
"They are equivalent because when x = 2, the two expressions have the same value."
We can solve this by multiplying those two numbers but we place them in improper fraction.
2 1/2 x 2 1/4
becomes
5/2 x 9/4
for fraction multiplication, just multiply numerator by numerator and denominator by denominator
5/2 x 9/4 = 45/8
we can simplify this into mixed fraction while numbers in whole numbers and remainder in numerator
5 5/8 is the answer
So all you have to do is multiply 400 times 400 which is 160,000 and divide 169,000 to 2 which is 80,000
Correct the first way is 1to1, 1:1, 1 boy to 1 girl .
