Question 153949
Let {{{x}}}= slices of turkey LAST YEAR
And 400% of  {{{x}}} you eat this year that equals to {{{12 slices}}}, putting it into eqn:
400%(x)=12 ------------------------> working eqn
continuing:
we know we divide 400 by 100 to use into the eqn,
{{{(cross(400)4/cross(100))(x)=12}}}
{{{cross(4)x/cross(4)=cross(12)3/cross(4)}}}
{{{x=3}}} --------------> no. of slices ate last year
To check, simlpy 400% of 3: {{{(cross(400)4/cross(100))(3)=12}}}
Thank you,
