To solve the equation 5/7 * x = 140, you need to isolate the variable x.
Step 1: Multiply both sides of the equation by 7 to eliminate the denominator of 5/7, so the equation becomes:
7 * (5/7) * x = 7 * 140
This simplifies to:
5x = 980
Step 2: Divide both sides of the equation by 5 to solve for x:
(5x) / 5 = 980 / 5
This simplifies to:
x = 196
Therefore, the value of x is 196.
From the given options, option B. 196 matches the value of x, so the correct answer is B.
multiply both sides by 7
then divide both sides by 5
