1.)cameron uses color film for 48out of every 72 photographs he takes. if he takes 156 photographs, how many will be on color film?
a.72
b.104
c.156
d.234
e.276

B. 104

Step-by-step explanation:

Since the problem gives an initial ratio of 48 out of 72, color to total photographs, we can set up a proportion, or equivalent ratios to solve for the amount of color film in 156 photographs:

cross-multiply: 72x = (48)(156)  or 72x = 7488

divide and solve: 72x/72 = 7488/72

x = 104 color film photographs

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
