what is 14/J= 42/12
14/J= 42/12
42(J) = 14(12)
42J = 168
J = 4
14/J= 42/12
Cross multiply and solve for J.
42J = 168
J = 4
To solve the equation 14/J = 42/12, we can use cross-multiplication.
When cross-multiplying, we multiply the numerator of the first fraction (14) by the denominator of the second fraction (12), and then multiply the numerator of the second fraction (42) by the denominator of the first fraction (J).
So, we have:
14 * 12 = 42 * J
To simplify, we can multiply 14 by 12 to get 168:
168 = 42 * J
Next, we divide both sides of the equation by 42 to isolate J:
168 / 42 = J
Simplifying further, we have:
4 = J
Therefore, the value of J that satisfies the equation 14/J = 42/12 is J = 4.
