9) 4 = K/42 Solve that for me pls I’m writing here because I need twenty words

DaniilM [7]

Answer:

k = 168

Step-by-step explanation:

$4= \frac{k}{42}$ rewrite the equation

$42 * 4=\frac{k}{42} *42$ Multiply 42 to isolate k. Do the same on the other side

42 * 4 = 168 When you do that you get 168.

Which of the following numbers is proportional to 84/108?

lara [203]

Proportional numbers are numbers with the same equivalent ratio

98/126 is proportional to 84/108

The number is given as:

$Number = \frac{84}{108}$

Reduce fraction to the lowest term

$Number = \frac{7}{9}$

Reduce 86/110 to the lowest term

$Number = \frac{86}{110}$

Divide by 2/2

$Number = \frac{43}{55}$

43/55 is not equivalent to 7/9

Reduce 98/126 to the lowest term

$Number = \frac{98}{126}$

Divide by 14/14

$Number = \frac{7}{9}$

7/9 is equivalent to 7/9.

Hence, 98/126 is proportional to 84/108
