Solve for the variable in 7 ∕28 = 25∕ x A. 20 B. 100 C. 4 D. 5
Answers
The solution to the equation 7/28 = 25/x is x = 100.
What is the solution to the equation?
Given the equation in the question:
7/28 = 25/x
To solve for the variable x in the equation 7/28 = 25/x, first, we cross multiply.
7/28 = 25/x
Cross-multiplying, i.e multiplying the numerator of the first fraction with the denominator of the second fraction and vice versa:
Hence:
7 × x = 28 × 25
7x = 700
Now, isolate x by dividing both sides by 7:
7x/7 = 700/7
x = 700/7
x = 100
Therefore, x has a value of 100.
Option B) 100 is the correct answer.

To round 494.37 to 1 significant figure, it becomes 400. To round 5.12 to 1 significant figure, it becomes 5. When we divide 400 by 5, we get 80.
For rounding 1 significant figure, we look at the first non-zero digit in the number. In this case, the first non-zero digit is 4. We keep that digit and drop all the digits to the right of it. So, 494.37 becomes 400.
Similarly, for 5.12, the first non-zero digit is 5. We keep that digit and drop all the digits to the right of it. So, 5.12 becomes 5.
Now, we divide 400 by 5, which gives us 80.
