Question

Javed's camera is loaded with a new roll of film. The film can take
72 exposures. During the class picnic, he took 48 pictures. What part of
the film is left to be exposed? Express this as a rational number as well a
decimal number​

Answer 1

Answer:

Part of film left to be exposed is 1/3 (as a rational number) and 0.33 (as a decimal number).

Step-by-step explanation:

Total number of exposures = 72

Total number of pictures taken (exposures made) = 48

=> Total number of unexposed exposures = 72 - 48 = 24

Part of unexposed film =

Total number of unexposed exposures ÷ Total number of exposures

= 24 ÷ 72

= $\frac{1}{3}$              (Expressed as a rational number)

= 0.3333    (Expressed as a decimal)

Answer 2

Step-by-step explanation:

First we have to subtract no. of pictures exposed - no. pictures taken. 72-48

then to find the unexposed film we have to decide no. of unexposed film / no. of film exposed that is 24÷72

then we have to convert it to rational number and decimal number
