45 * ? = 35% of 900

To solve the equation "45 * ? = 35% of 900," we need to find the value of the missing number.

Step 1: Convert 35% to a decimal by dividing it by 100. 35% = 35/100 = 0.35

Step 2: Multiply 0.35 by 900 to find the value of 35% of 900. 0.35 * 900 = 315

Step 3: Set up the equation "45 * ? = 315" and solve for the missing number. 45 * ? = 315

To find the value of the missing number, we can divide both sides of the equation by 45. (45 * ?) / 45 = 315 / 45

Simplifying the equation gives us: ? = 7

Therefore, the missing number is 7.
