Answer:
Step-by-step explanation:
Person who wears a watch + ring
Lets say the fraction of people wearing the rings is 1/X
Lets say the fraction of people wearing a watch is 2/y
The formula is multiplication for both (Key words: and)
The formula is add for one or the either (key words: or)
The question says that person wears a watch given that they wear a ring
It mean that they wear a watch + a ring.
THat mean multiplication!
Lets use the example: 1/x · 2/y = 2/xy
This makes 2/xy your answer for the example.
Now lets do another example:
Lets say the fraction of people wearing the rings is 1/3
Lets say the fraction of people wearing a watch is 2/3
Multiplication!!!!
1/3 x 2/3 = 2/9
This makes 2/9 your answer to this example!!!!

Answer:
-8
Step-by-step explanation:
According to question,
(-x) + (-x)(1/4) + (-x)(7/16) = -13 1/2
-x - x/4 -7x/16 = -27/2
Now, make all denominators equal:
(-16x -4x - 7x)/16 = -27/2
Now, multiply both sides with 16 to get rid of denominator:
-16x - 4x - 7x = -216
-27x = -216
-x = -216/27
= -8
Sorry for delay
