the masses of John,Gregory and Ethan are 38 1 out of 5,41 1 out of 3 and 52 1 out of 4.find the total mass of the three children.give your answer as a mixed number in it's simplest form.
+36916 I THINK this what you are asking: 38 1/5 + 54 1/3 + 52 1/4
add the red parts = 144
now the fractions..... the lcm of 5 3 and 4 is 60 1/5 = 12/60 1/3 = 20/60 1/4 = 15/60
added together = 47/60
then 144 + 47/60 = 144 47/60 (kg ?)
