<PRE><B>Question 175374</B>
again in order to add or subtract fractions we have to find LIKE denominators.
:
5(1/2)=5/2=
6(1/3)=6/3=2
4(1/4)=4/4=1
:
since 5/2 has a denominator of 2 lets write the rest of the numbers giving them a denominator of 2
:
2 multiplying top and bottom by 2 = 4/2
1 multiplying top and bottom by 2 = 2/2
:
{{{5/2+4/2+2/2=11/2}}}or 5 and 1/2 hours they worked</PRE>
