explain why
To solve the proportion x/8 = 30/40, we can cross-multiply.
Multiplying both sides of the equation by 8 gives us:
x = (30/40) * 8
Simplifying the right side by multiplying 30/40 by 8 gives us:
x = (3/4) * 8
Multiplying 3/4 by 8 gives us:
x = 6
Therefore, x equals 6.
Explanation: The proportion x/8 = 30/40 means that the ratio of x to 8 is equal to the ratio of 30 to 40. To solve for x, we can use cross-multiplication. By multiplying both sides of the equation by 8, we can isolate x on one side. Then, simplifying the right side by multiplying 30/40 by 8 gives us the value of x. In this case, x equals 6.
