Answer:
I think its better than other types of math.
Step-by-step explanation:
Q1
the clothes are on 45% discount, wich mean they become 55% of their original price.
30× 55% =16.5
64×55%=35.2
the new salary is 103% of the original
10×103% = 10.3
11600×103% = 11,948
Q2:
1+0.24= 1.24
1- 0.27= 0.73
86×140%= 120.4
440×119%= 523.6
82×90% = 73.8
480× 73%= 350.4
(17-5=12-1=11+8=19-2=(17-3=14)-3=11-3=8-3=5) wait maybe I got this mixed up with somthing else but...
