Question

multiply both sides:multiply both sides by what?
$7.2(\square)=3.6x(\square)$

Explanation:

Step1: Identify goal

We aim to simplify the equation by eliminating decimals, so we need to find a number to multiply both sides by that converts 7.2 and 3.6 to integers.

Step2: Determine the multiplier

The smallest number that eliminates the tenths place decimal is 10, since $7.2 \times 10 = 72$ and $3.6 \times 10 = 36$, both integers. We can also use any multiple of 10 (like 100, 20, etc.), but 10 is the simplest.

Answer:

The blanks can be filled with 10 (or any multiple of 10, e.g., 20, 100). The most straightforward answer is:
Left blank: $10$, Right blank: $10$
