A Tyrannosaurus rex ate half of a small triceratops it had hunted. When it left, a pack of velociraptors scavenged half of what was left. A group of lazy Allosaurus gulped down the last 270 kilograms of meat. How many kilograms of meat were on the triceratops before the T-Rex ate?
assistant
How many kilograms of meat did the T-Rex leave? ** The velociraptors left half for the Allosaurus, so the T-Rex left 2 * 270 = <<2*270=540>>540 kilograms of meat.
How many kilograms of meat were on the triceratops before the T-Rex ate? ** The T-Rex ate half the meat, so there were 540 * 2 = <<540*2=1080>>1080 kilograms of meat on the triceratops.
