Answer:
64 ivy stems
Step-by-step explanation:
To solve this problem we can use rule of three:
Firstly we had 72 ivy stems to use in 18 centerpieces, and know we have 16 centerpieces and want to know how many ivy stems we need to use, so:
18 centerpieces -> 72 ivy stems
16 centerpieces -> X ivy stems
18/16 = 72/X
X = 16*72/18 = 64
He needs to use now 64 ivy stems to maintain the ratio.

Answer:
the estimated difference is 4
Step-by-step explanation:
The estimated difference of 12 9/11 - 8 13/15 would be rounding the fractions to a whole number
12 9/11 becomes 12 11/11 which is 13
8 13/15 becomes 8 15/15 which is 9
we rounded each fraction up since each fraction was above the half way mark so the new equation is,
13 - 9 = 4
