2/5+2/3+3/4 = 24/60 + 40/60 + 45/60 = 109/60
\(\dfrac{2}{5}+\dfrac{2}{3}+\dfrac{3}{4}=\dfrac{16}{15}+\dfrac{3}{4}=\dfrac{109}{60}\)
\(\dfrac{\text{2}}{5}+\dfrac{2}{3}+\dfrac{3}{4}=\dfrac{6}{15}+\dfrac{10}{15}+\dfrac{3}{4}=\dfrac{16}{15}+\dfrac{3}{4}=\dfrac{64}{60}+\dfrac{45}{60}=\dfrac{109}{60}\)
2/5 + 2/3 + 3/4 = 24/60 + 40/60 + 45/60 = 109/60
