To find the total fractional amount of the desired funds raised, we need to add the fractions from the bake sale and the yard sale.
The bake sale raised \( \frac{3}{8} \) of the desired funds, and the yard sale raised \( \frac{1}{4} \) of the desired funds.
First, we convert \( \frac{1}{4} \) to have a common denominator with \( \frac{3}{8} \). The common denominator for 4 and 8 is 8:
\[ \frac{1}{4} = \frac{2}{8} \]
Now we can add the two fractions:
\[ \frac{3}{8} + \frac{2}{8} = \frac{3 + 2}{8} = \frac{5}{8} \]
Thus, the total fractional amount of the desired funds they have raised is:
\[ \frac{5}{8} \]
So the correct response is:
58 Start Fraction 5 over 8 End Fraction.
