Final answer:
To solve for y in the equation 3/17 = y/7, cross-multiply and divide to get y = 21/17, which is approximately 1.235294117647 when converted to a decimal. Rounding this to the nearest tenth gives us y ≈ 1.2.
Step-by-step explanation:
The question asks us to solve for y in the equation 3/17 = y/7, and then to round the solution to the nearest tenth. To find y, we can use cross-multiplication. We multiply both sides of the equation by 7 to isolate y on one side:
3/17 * 7 = y
Using a calculator, we get:
(3 * 7) / 17 = y
y = 21/17
Now, let's convert this fraction to a decimal to round it to the nearest tenth:
y ≈ 1.235294117647...
When rounding to the nearest tenth, we look at the number in the hundredths place which is 3. Since it's less than 5, we do not round up. Therefore, y rounded to the nearest tenth is:
y ≈ 1.2
