Answer:
16 and 21/44 or 725/44
Step-by-step explanation:
convert 6 and 1/4 into an improper fraction; 25/4
convert 2 and 7/11 into an improper fraction; 29/11
multiply them together.
× 
you can do 25 × 29 to get 725
you can also do 4 × 11 to get 44.
725/44 simplifies to 16 and 21/44.
Just cross multiply to find 18% of 430
18/100 = x/430
430 X 18 = 7740
7740 = 100x
7740/100 = 77.4
so Melcher took about 77 photos.
B
Multiply 35% by 200 and get 70
Add that 70 to 200 and you’ll get B which is 270
