three friends share a bag of erasers. Mary get 1/5 of the eraser. Helen gets 3 more erasers then mary and Sylvia gets 12 erasers.How many erasers are in the bag ?
4/5 of the share belongs to Helen and Sylvia Difference in total share is= 4/5-1/5 =3/5 So 3/5=12+3 =15 3 units is 15 Thus 1 unit is 15/3 which is 5 And 5 units is 25(5*5) I am not too sure though Sorry
