Answer:
7 1/2
Step-by-step explanation:
try putting (1.6 x 7.5)+48 in a calculator i just put random numbers in the x spot until i got 60 lol
original quantity : 10 for $1
new quantity: 4 for $1
now we have to find each percent change
10-4=6
6÷100=0.06
0.06=6%
the quantity went down 6%
Luis = 6/7
Marrisa = 5/9
Federico = 11/10 = 1 1/10
Greatest fraction = 1 1/10
Answer: Frederico raised the most.
