Question

Jordan places two boards end to end to make one shelf. The first board is 47-100 meter long.The second board is 5-10 meter long. What fraction is equivalent to 5-10 and has a denominator of 100.

Answer 1

The fraction that is equivalent to 5-10 and has a denominator of 100 is:

(50) / (100)

Answer 2

We have the following fraction:
(5) / (10)
In order not to alter the expression, we must multiply the numerator and denominator by the same factor k:
(5 * k) / (10 * k)
Since we know that the denominator is 100 then:
10 * k = 100
Clearing:
k = 100/10
k = 10
Substituting:
(5 * 10) / (10 * 10)
Rewriting:
(50) / (100)
Answer:
The fraction that is equivalent to 5-10 and has a denominator of 100 is:
(50) / (100)
