Answer:
a.) transitive property of equality
Step-by-step explanation:
1/20= 1 divided by 20= 0.05
I turn the mixed numbers into decimals before doing anything else.
11 2/5----> 57/5----> 11.4
4 2/7----> 30/7----> 4.29
2 1/7----> 15/7----> 2.14
11.4=q-4.29+2.14
11.4=q-2.15
13.55= q
13.55 converted to a fraction is 13 11⁄20
q=13 11⁄20
Because normally you don't cut posters into thirds. You keep them as whole numbers therefore fractions make no sense
