Question

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

Answer 1

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.
