Answer:
The number of shirts that Cameron's Brother has is:
C. 12 Shirts
Explanation:
Cameron has 75% as many shirts as her brother.
let the number of shirts Cameron has be= C
let the number of shirts Cameron's brother has be= B
Then, C=9 (Given)
Since,
Cameron has 75% as many shirts as her brother.
So,
C=75/100 X B
9=75/100 X B
9X100/75=B
B=9X100/75
75/100 can be reduced to the fraction 3/4,
as 75= 25X3 and 100=25X4
Thus,
B=9X100/75
B=9X4/3
3 cancels 9 to leave 3,
Thus,
B=3X4
B=12
So,
Answer=12 Shirts
Number of shirts that Cameron's Brother has are 12
