5:15 and x:3
a.5
b.3
c.1
5:15 = x:3
Cross multiply and solve for x.
I'll be glad to check your answer.
so what i multiply
Multiply:
5 * 3
15 * x
15x = 15
i don't get it
5 time 3 15
and 15?
so its 3
x = 15/15
x = 1
okay help me
Huh?? I told you the answer? What more do you want????
To find the value of x, we can set up a proportion using the given information:
The ratio of 5:15 is the same as the ratio of x:3.
This can be written as: 5/15 = x/3.
Now, we cross-multiply to solve for x:
(5 * 3) = (15 * x)
15 = 15x
Next, divide both sides of the equation by 15 to isolate x:
15/15 = x
1 = x
Therefore, the value of x is 1 (option c).
