Quizplus · Accepted Answer

To solve $7 \frac { 5 } { 36 } - 4 \frac { 1 } { 30 }$, first convert the mixed numbers to improper fractions: $\frac{253}{36} - \frac{121}{30}$. Find a common denominator, which is 180, and convert: $\frac{1265}{180} - \frac{726}{180}$. Subtracting these gives $\frac{539}{180}$, which simplifies to $3 \frac { 19 } { 180 }$.
