Franz and Leah encountered an asteroid field. Franz blasted about 1/6 of the asteroids and Leah blasted about 1/4 of the asteroids. Who blasted the most asteroids and what fraction of the asteroid field remains and why.
Help Please

Leah blasted the most asteroids and the fraction that remains is 7/12 because if you add up the fractions they blasted, it would be 5/12 and there is 7/12 left over from that.
