    The answer is NOT B. I'll explain in my next post.

    Since any number divided by itself equals 1, you can rewrite 1 as a fraction, e.g. \[1 = \frac{2}{2} = \frac{3}{3} = \frac{6}{6}\] Any whole number can be rewritten as a fraction by multiplying it by 1 in the form of a fraction. 5 can be made into a fraction like so: \[5 * 1 = 5*\frac{3}{3} = \frac{15}{3}\] \[5\frac{1}{3} = \frac{15}{3} + \frac{1}{3} = \frac{15+1}{3} = \frac{16}{3}\]

    Similarly, fractions can also be rewritten by multiplying them by 1 in the form of a fraction. In this case we'll need to multiply it by something to get the denominator to equal 18. What fraction do you think it should be @HammerG ?

    Nope. If you show your work I can help you figure out where you went of the rails, so to speak.

    5 and one third minus three and nine eighteenths cannot possibly be B. Even Wolfram Alpha agrees with me.

    that term value comes out to (16/3)-(63/18) =1.833

    \[\huge 5 \frac{1}{3} = \frac{16}{3}\] \[\huge -3\frac{9}{18} \implies -3\frac 12 = -\frac{7}{2}\] \[\huge \frac{16}{3} - \frac{7}{2} = \frac{32}{6} - \frac{21}{6}\]

    another big flaw@igbasallote..it is not fraction to cancel like that(3 9/18)...it is a mixed fraction

    \[\frac{9}{18} = \frac{1}{2}\] \[3\frac{1}{2} = \frac{6}{2}+\frac{1}{2}=\frac{7}{2}\] \[\frac{16}{3}+-\frac{7}{2} = \frac{16}{3}-\frac{7}{2} = \frac{32}{6}-\frac{21}{6} = \frac{11}{6}=1\frac{5}{6}\] @Raja99 What are you talking about? We KNOW it's a mixed fraction, hence why we're showing our work converting it to fractions, giving them equal denominators, and then adding them together and turning them back into a mixed fraction!

    All I can tell you is that @lgbasallote and I got the same answer, Wolfram Alpha got the same answer, and we showed how we got it, whereas Raja99 hasn't shown any of his work.
