    so -(23/5)-(5/2)=-(46/10)-(25/10)=-71/10

    ok multiply 5 by 4 and then add 3 for first fraction to get -23/5

    the quickest way to think about it is to multiply the denominator by the whole number the add the numerator. the get common denominators before anyting else

    • one year ago
  14. akhaliq99 Group Title

    you get the numerator that way over the same denominator

    • one year ago
  15. Benbburn Group Title

    so like x(a/b) = (bx+a)/b

    do same for second fraction to end up with improper fractions

    • one year ago

    so I have to find the common denominator before anythiing

    i would get them to imporper fractions before common denominators

    yes then find common denominator if it is not already there.

    first. convert mixed number to improper fraction second. get common denominator if needed third. solve

    then the denominators should be 10 right
