• is there an esyer way to do 5 times 47 or not
• how is a fraction simplified
• First, find the highest number that can divide into both the numerator and denominator exactly. Then divide the numerator and denominator by that number. If it's an improper fraction (the numerator is larger than the denominator), make it a mixed number. :)
