Finding the value of m in proportion

Given, 3, 18, m, 42 are in proportion.

To find the value of m, we need to use the property of proportionality.

The property states that if four quantities a, b, c, and d are in proportion, then:

a/b = c/d

We can use this property to find the value of m.

Solution

We can write the proportion as:

3/18 = m/42

To solve for m, we can cross-multiply:

3 x 42 = 18 x m

126 = 18m

Dividing both sides by 18, we get:

m = 7

Therefore, the value of m, if 3, 18, m, 42 are in proportion is 7 (Option C).

Final Answer: Option C - 7
