When multiplying a number by 100, you're essentially shifting the decimal point two places to the right. So, for \(3,07 \times 100\), you simply move the decimal from after the 3 to after the 7, resulting in \(307\)! Now, for \(5,182 \times 1000\), it's a similar trick but with three places. Move the decimal three spots to the right from \(5,182\) to get \(5,182,000\). Isn't it fun how just a little movement can change numbers so drastically?
