Question

Solve the following proportion (11)/(17) = (u)/(7)

Round your answer to the nearest tenth.
X =____

Answer 1

To solve the proportion 11/17 = u/7, we cross multiply to find u = (11 * 7) / 17, which simplifies to approximately 4.5 when rounded to the nearest tenth.

Step-by-step explanation:

To solve the proportion 11/17 = u/7, we use cross multiplication to find the value of u. Here's the step-by-step process:

1. Multiply the numerator (top number) of the first fraction by the denominator (bottom number) of the second fraction: 11 * 7.
2. Multiply the denominator of the first fraction by the numerator of the second fraction: 17 * u.
3. Set the two products from steps 1 and 2 equal to each other: 11 * 7 = 17 * u.
4. Solve for u by dividing both sides by 17: u = (11 * 7) / 17.

Performing the calculation, we get:

u = (77) / 17 which is approximately 4.5 when rounded to the nearest tenth.

So, after rounding to the nearest tenth, the value of u is 4.5.
