A factory worker conducted a test on a random sample of 150 products. I love the products tested, 2 were found to have defects.
VikaD [51]
So what you would do is 3000 divided by 150 which is 20 then you would multiply 20 by 2 which is 40 so 40 is most likely defective.

Alison knits 1/10 of scarf in 4/5 of an hour. what fraction of a scarf can alison knit in 1 hour? and how do u solve it?
pav-90 [236]
For this case we can make the following rule of three:
 1/10 scarf ------> 4/5 hour
 x ------------------> 1 hour
 Clearing the value of x we have:
 x = (1 / (4/5)) * (1/10)
 Rewriting we have:
 x = (5/4) * (1/10)
 x = 5/40
 x = 1/8
 Answer:
 
A fraction of a scarf that alison can knit in 1 hour is:
 
x = 1/8

Simplify this expression and show all steps:<br> 48m^7/20m^4
Ghella [55]

Answer:

(12/5)m^3

Step-by-step explanation:

It's easier for most of us to write out a fraction / ratio without the " / " symbol:

48m^7

------------

20 m^4

Separate the coefficients from the powers of m:

48     m^7

----- * --------     Now let's reduce each fraction separately:

20      m^4


48/20 = 12/5, and

(m^7) / (m^4) = m^(7-4) = m^3


... so that our final answer is (12/5)m^3.
