To find the number of black and white photos from a total of 600 pictures where 12% are black and white, you need to multiply the total number of pictures by the percentage of black and white photos.
The calculation can be expressed as:
\[ \text{Number of black and white photos} = 600 \times \frac{12}{100} \]
To see if any of the provided equations match, let's analyze them:
-
StartFraction 600 divided by 6 Over 12 divided by 6 EndFraction = StartFraction 100 Over 2 EndFraction
This equation doesn't correctly represent the problem. -
StartFraction 12 times 6 Over 100 times 6 EndFraction = StartFraction 72 Over 100 EndFraction
This equation simplifies to \( \frac{72}{100} \), which is equivalent to 72% of something, not the number of black and white photos. -
StartFraction 600 divided by 12 Over 600 divided by 100 EndFraction = StartFraction 50 Over 6 EndFraction
This equation doesn't work for this problem as it doesn’t correspond to finding 12% of 600. -
StartFraction 600 + 12 Over 100 + 12 EndFraction = StartFraction 612 Over 112 EndFraction
This equation does not fit with determining the number of black and white pictures either.
None of the provided equations directly express the correct procedure for finding 12% of 600, which should be written as:
\[ \text{Black and white photos} = 600 \times 0.12 \]
This results in:
\[ 600 \times 0.12 = 72 \]
Thus, the number of black and white photos is 72. The correct equation is not presented in the options you've provided.
