0.4 Times 97.5 Plus 0.25 Times 99.34: A Simple Breakdown

Mathematics can sometimes seem daunting, but breaking down problems step by step makes it easier to understand. Today, we’re going to solve the expression 0.4 × 97.5 + 0.25 × 99.34 and explore why this kind of problem is useful in daily life. Whether you’re calculating expenses, working with measurements, or just learning how to multiply and add decimals, mastering these basic operations is essential.

Breaking Down the Equation

First things first: let’s understand the problem. The equation at hand is 0.4 × 97.5 + 0.25 × 99.34. This might look a little tricky at first glance, but once we break it into manageable chunks, the solution becomes much clearer.

Step 1: Multiply 0.4 by 97.5

To begin, let’s tackle the first part of the equation: multiplying 0.4 by 97.5.

Multiplication with decimals is simple if you remember a few rules. You treat it like regular multiplication, ignoring the decimal point initially. After multiplying, you place the decimal point where it belongs.

Let’s go ahead and multiply 0.4 × 97.5:

$$0.4\times 97.5=39$$

So, the first part of our equation equals 39. Pretty straightforward, right?

Step 2: Multiply 0.25 by 99.34

Now, let’s move on to the second part of the equation: multiplying 0.25 by 99.34. Similar to the first part, we’ll ignore the decimal at first and multiply the numbers as if they were whole numbers.

$$0.25\times 99.34=24.835$$

The result of this multiplication is 24.835. That’s the second piece of our puzzle.

Step 3: Adding the Two Results

We now have two results: 39 from the first part and 24.835 from the second part. To complete the equation, we need to add these two numbers together:

$$39+24.835=63.835$$

So, the final result of 0.4 × 97.5 + 0.25 × 99.34 is 63.835.
