On easter morning 20 eggs were hidden kyla found 1/2 of them kevin found 1/4 of them what fraction of eggs were left to find
kotykmax [81]
\frac{1}{2}*20= 10 &#10; and \frac{1}{4}*20= 5
This means that Kayle found 10 eggs while Kevin found 5 eggs.
so 20-(10+5)= 5 eggs left.
To find the fraction, divide the number of eggs left over the number of total eggs.
Fraction= \frac{5}{20}= \frac{1}{4}

Hope this helps!
