Understanding Decimal Numbers in Word Form

The video tutorial explains how to write the number 63.15 in word form. It begins by addressing the whole number part, which is straightforwardly written as 'sixty-three.' The tutorial then discusses the decimal point and the fractional part, offering two ways to express it: 'one tenth and five hundredths' or 'fifteen hundredths.' The latter is preferred for simplicity. The video further explains how to add fractions by finding a common denominator, demonstrating that 1/10 plus 5/100 equals 15/100, thus justifying the expression 'sixty-three and fifteen hundredths.'
