The Deep Dive
To divide \( 5.2 \) by \( 0.16 \) using unit form, you'll first convert both numbers to whole numbers by shifting the decimal point. This means you can rewrite \( 5.2 \) as \( 52 \) and \( 0.16 \) as \( 16 \) (moved the decimal two places to the right for both). So, now you have \( 52 \div 16 \). The calculation gives \( 3.25 \) when you divide. So, expressed in standard form, the answer is \( 3.25 \). To double-check your math, consider the multiplication approach! Multiply \( 3.25 \) by \( 0.16 \) to see if you get back to \( 5.2 \). This practice can help confirm your answer and solidify your understanding of the relationship between division and multiplication!
