a) \( 1.44 \div 1.2+6.2 \)

Did you know that dividing decimals can be as simple as turning them into whole numbers? You can multiply both the numerator and the denominator by 10 to eliminate the decimal. So, \( 1.44 \div 1.2 \) becomes \( 14.4 \div 12 \). This gives you \( 1.2 \) before adding \( 6.2 \), which results in \( 7.4 \). When adding and dividing decimals, it's helpful to line them up vertically to avoid any confusion. That way, you can easily see where each digit goes! For example, when you have your final results, you can neatly add \( 1.2 \) and \( 6.2 \) to reach your answer: \( 7.4 \)! Just remember to check for those pesky decimal points!
