Mathematics Knowledge
Yesterday I presented an algebra problem that consisted of a fraction.
The question was: If 5/6x = 30, what does x equal?
As an ASVAB tutor, algebra with fractions is one of the 15 subtopics I cover in the Mathematics Knowledge section of the ASVAB. I remind my students that this problem is not as challenging as it seems.
To solve the problem 5/6x = 30, it is necessary to get rid of the fraction in front of the variable.
When there is fraction in front of a variable, you need to multiply by the reciprocal on both sides of the equal sign.
5/6 = 30
6/5 times 5/6 x= 30/1 times 6/5
6/5 times 5/6 cancels out leaving only x
x = 180/5
x = 36
The answer is 36.
Did you know how to solve this problem?
