Answer:
Each Grandchild got 0.15 part of her collection
Step-by-step explanation:
let the total doll collection that 1 grandchild got be x
then, both the grandchildren will get 2x
0.7 = 70/100 = 70%
Gn:
out of 100% of dolls, 70% went to the orphanage.
therefore, 100% - 70% = 2x
30% = 2x
30/(100 * 2) = x
30/200 = x
0.15 = x
Therefore, each grandchild got 0.15 of the doll collection
