Question 6 options:

Evaluate this expression.

fraction numerator a over denominator 5 end fraction comma text   end text i f star times text   end text a star times equals text   end text 450

To evaluate the expression, we need to substitute "a" with its corresponding value in the given equation "a*5 = 450".

a*5 = 450

Dividing both sides of the equation by 5, we can find the value of "a".

a = 450/5
a = 90

Now, we can substitute the value of "a" (which is 90) into the initial expression:

fraction numerator a over denominator 5 end fraction

This becomes:

fraction numerator 90 over denominator 5 end fraction

Simplifying the fraction, we divide the numerator (90) by the denominator (5):

90/5 = 18

Therefore, the expression evaluates to 18.

To evaluate the expression, we need to find the value of "a" that satisfies the equation "a * 5 = 450".

To solve for "a", we can divide both sides of the equation by 5.

450 / 5 = 90

So, the value of "a" that satisfies the equation is 90.

Therefore, the expression evaluates to:

fraction numerator 90 over denominator 5 end fraction

or

90/5

To evaluate the given expression, we need to substitute the value of 'a' that satisfies the equation "a*5 = 450" into the expression.

Let's solve the equation first:
a * 5 = 450

To isolate 'a', we divide both sides of the equation by 5:
(a * 5) / 5 = 450 / 5
a = 90

Now that we have the value of 'a' (which is 90), we can substitute it into the original expression and evaluate it:

fraction numerator a over denominator 5 end fraction

Replacing 'a' with 90:
fraction numerator 90 over denominator 5 end fraction

Evaluating the expression above:
90 divided by 5 equals 18

Therefore, the value of the expression "fraction numerator a over denominator 5 end fraction" when a is 90 is 18.
