7/x = 1/6... Solve X?

Question

Explain

Answer 1

7 = x / 6
42 = x

Answer 2

If 7/x = 1/6, you can multiply each side by x to get:

7 = x / 6.

Then multiply each side by 6 and you get x = 42.

Answer 3

7/x = 1/6

Since x is the denominator, flip both terms over:
x/7 = 6/1
x/7 = 6

Multiply both sides by 7:
x = 7 x 6
x = 42

Answer 4

7 1
-- = -----
x 6

7/x is proportional to 1/6
cross multiplying will help you figure out what the x value is

so to cross multiply you start with your known values
7*6 or 42 then 42/1 or 42
x=42
so 7/42 is proportional to 1/6

you can check this by looking at their decimals
7/42=1.66666667
1/6=1.66666667

Answer 5

x = 42

Answer 6

7/x = 1/6
x*1=6*7
x=42

Answer 7

7/x = 1/6

x=6*7

x=42

Answer 8

7/x=1/6
cross multiply
i.e. multiply by 6 on the left hand side and by x on the right hand side.
therefore th equation becomes;
42=x this means that x=42

Answer 9

Think of the expressions on both sides of the equation as simple ratio and proportion.
7:x = 1:6 (Eq. 1)
Use the following formula as your basis:
A:B = C:D (Eq. 2)
Perform multiplication of the ratios:
(B)(C) = (A)(D) (Eq. 3) (Hint: Inner x Inner; Outer x Outer)
or (A)(D) = (B)(C)
Always place the literal coefficient at the left side of the equation.
Perform substitution:
From Eq. 1:
A = 7
B = x
C = 1
D = 6
(x)(1) = (7)(6)
x = 42 (Answer)
