First expression: (-7)/(-4)
Divide. Note that two negative numbers divided will result in a positive answer
(-7)/(-4) = 7/4 = 1.75
First expression: Greater than 1.
-----------------------------------------------------------------------------------------------------------------
Second expression: -(3/2)
Simplify: 3/2 = 1.5
-(1.5) = -1.5
Second expression: Less than -1
--------------------------------------------------------------------------------------------------------------
Third expression: (-8/5) x (-5/8)
Note that two negatives = one positive answer when multiplying
8/5 x 5/8 = 40/40 = 1
Third expression: Neither
----------------------------------------------------------------------------------------------------------------
Fourth Expression: (-5)/(-3)
Divide: (-5)/(-3) = 5/3 = ~1.67
Fourth Expression: Greater than 1
----------------------------------------------------------------------------------------------------------------
Fifth Expression: (-9)/6
Divide: (-9)/6 = -1.5
Fifth expression: Less than -1
----------------------------------------------------------------------------------------------------------------

A product is made up of components A, B, C, D, E, F, G, H, I, and J. Components A, B, C, and F have a 1/10,000 chance of failure

Answer:
The overall reliability is 99.7402 %
Step-by-step explanation:
The overall reliability of the product is calculated as the product of the working probability of the components.
For components A,B,C and F we have :
⇒
For components D,E,G and H we have :
⇒
Finally, for components I and J :
⇒
Now we multiply all the working probabilities. We mustn't forget that we have got ten components in this case :
Components A,B,C and F with a working probability of 0.9999
Components D,E,G and H with a working probability of 0.9997
Components I and J with a working probability of 0.9995
Overall reliability = 
0.997402 = 99.7402 %

is this you¿¿??????¿¿!!!!!!
Answer:
<h2>OPTION B IS THE CORRECT ANSWER</h2>
Step-by-step explanation:
1)a^7/a^4
=a^[7-4]
=a³
2) r²s⁴t/r²st³
=s⁴-¹.t¹-³
=s³.t-²
=s³/t²
3)3x^6/18x
=x^5/6
