vidéo : Transformer un Nombre Décimal en Fraction Décimale (et vice versa)

This video is about how to convert a decimal number to a fraction and vice versa. In the first part of the video, we learn how to convert a decimal number to a fraction. We do this by first identifying the place value of the last digit of the decimal number. If the last digit is in the tenths place, the denominator of the fraction will be 10. If the last digit is in the hundredths place, the denominator of the fraction will be 100. And so on. The denominator of the fraction will be 10 times greater for each place value to the right of the decimal point. Once we have identified the denominator of the fraction, we can find the numerator by simply removing the decimal point from the decimal number. The numerator of the fraction will be the same as the decimal number without the decimal point. In the second part of the video, we learn how to convert a fraction to a decimal number. We do this by first identifying the denominator of the fraction. The denominator of the fraction tells us how many places to the right of the decimal point we need to move the decimal point. Once we have identified the number of places to move the decimal point, we can simply move the decimal point that many places to the right. The resulting number will be the decimal equivalent of the fraction. I hope this video has been helpful!
