Put these fractions over a common denominator: \(\frac{3}{5}\) and \(\frac{4}{7}\).
Answer (3)
3/5 x 7/7= 21/35 4/7x 5/5= 20/35 They both have a common denominator
To put the fractions ³/5 and 4/7 over a common denominator, find the least common multiple (LCM) of 5 and 7, which is 35. Multiply the numerator and denominator of each fraction by the appropriate factor to obtain fractions with a denominator of 35. ;
To find a common denominator for 5 3 and 7 4 , we determine the least common multiple, which is 35. We then adjust the fractions to get 35 21 and 35 20 . This allows us to compare or add the fractions easily.
