Macete para subtrair frações | método da borboleta

In today's video, we're going to share an amazing trick: "Trick for subtracting fractions - the butterfly method". This method greatly simplifies calculations, as it's not necessary to calculate the Least Common Multiple (LCM) to subtract fractions. With the butterfly method, simply cross-multiply the numerators and denominators of the fractions, subtract the results of the multiplications to obtain the new numerator, and multiply the denominators to obtain the new denominator. This trick makes subtracting fractions quick and practical, facilitating its learning and application. Learn this efficient technique and speed up your mathematical calculations!
