The amount of water is increasing by 3 while the amount of other two ingredients (yeast and hydrogen per oxide) is same.
Step-by-step explanation:
file is attached below in which the tape diagram of ratios is present.
amount of yeast use in making foam=1
amount of water use in making foam=3
amount of hydrogen per oxide in making foam=8
In part B we are using 3 more table spoons of water than yeast in making foam, now the amount of ingredients use in making foam is;
amount of yeast use in making foam=1
amount of water use in making foam=3(3)=9
amount of hydrogen per oxide in making foam=8
