To find the total yield of pumpkins in the two fields you must add the the 2 mixed numbers of the smaller yields.
[tex]3\frac{2}{5}+2\frac{1}{12}[/tex]convert the mixed numbers into fractions by mutiplying the denominator with the whole number and adding the numerator, to find the numerator. the denominator stays the same
[tex]3\frac{2}{5}=\frac{(3\cdot5)+2}{5}=\frac{17}{5}[/tex][tex]2\frac{1}{12}=\frac{(12\cdot2)+1}{12}=\frac{25}{12}[/tex]add both fractions together
[tex]\frac{17}{5}+\frac{25}{12}=\frac{17\cdot12+25\cdot5}{12\cdot5}=\frac{204+125}{60}=\frac{329}{60}[/tex]convert into a mixed number
[tex]\frac{329}{60}=5\frac{29}{60}[/tex]The total yield of pumpkins is
[tex]5\frac{29}{60}\text{tons of pumpkin}[/tex]
