The number of new calculators tested was 50 . . . 8 were bad and 42 were good.

The ratio of defective ones to new ones tested is 8:50 or 4:25 or 16% .

You simply put the 2 numbers together to find the answer, which is 8:42.  

You want to find the ratio in its simplest form.  Therefore, you want to find the lowest common multiple of 8 and 42.  
2 goes into both numbers.  
8 / 2 = 4.  
42 / 2 = 21

The answer is 4:21.

Work out the missing value in the calculation below​
fiasKO [112]

Answer:

5

Step-by-step explanation:

\frac{2}{3} +\frac{1}{6}= \frac{ }{6}  \\

Here LCM will be 6. (We made the denominator same)

so, now the equation will be :

\frac{2}{3}+\frac{1}{6}    \\\\  =\frac{4}{6} + \frac{1}{6}

= 5/6

So, the value in the red box is 5.

Hope it helps!

2,5 is just one of the many solutions to this problem. you can just take a random number for x, for example 2. your equation will look like this 3(2)-y=1. now you just solve for y. 3x2=6. 6-1=5. so y=5.
