Answer 1

What is the solution to the following proportion?

\[\frac{ 18 }{ 45} = \frac{ 2 }{ t }\]

Answer 2

A. t = 2.5

B. t = 5

C. t = 9

D. t = 36

Answer 3

Cross multiplication:
\[\frac{ 18 }{ 45} = \frac{ 2 }{ t }\]
\[18*t=45*2\]
\[18t=90\]
How would you proceed from here?/
We need to isolate t

Answer 4

ok

Answer 5

so whats the answer?

Answer 6

whoops sorry

Answer 7

O_O listen kid thats my best friend so if you wanna mess with her you mess with me so waz good -.-

Answer 8

Listen lemme mess with u :P

Answer 9

fine then forget it im done im going to guess on it byre

Answer 10

Step by step solution :

Step 1 :

2 2
Simplify — - —
5 t
Calculating the Least Common Multiplier :

1.1 Find the Least Common Multiple (L.C.M)

The left denominator is : 5

The right denominator is : t


Add the fractions that have a common denominator :

1.4 Add up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

2 • t - (2 • 5) 2t - 10
——————————————— = ———————
5t 5t
Pulling out like terms :

1.5 Pull out like factors :

2t - 10 = 2 • (t - 5)

Equation at the end of step 1 :

2 • (t - 5)
——————————— = 0
5t
Step 2 :

2•(t-5)
Solve ——————— = 0
5t
When a fraction equals zero :

2.1 When a fraction equals zero ...
Where a fraction equals zero, its nominator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

2•(t-5)
——————— • 5t = 0 • 5t
5t
Now, on the left hand side, the 5t cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :
2 • (t-5) = 0

Equations which are never true :

2.2 Solve : 2 = 0

This equation has no solution.
A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.3 Solve : t-5 = 0

Add 5 to both sides of the equation :
t = 5

Solution :

t = 5
