Answer: 1/6 = 4/24 1/4 = 6/24
Step-by-step explanation:
Multiply the denominators of the fraction so 6x24 is 24 so the common denominator is 24 now whatever you do to the bottom you do to the top so you do 1x4 which is 4 then that means your first fraction is 4/24 then you do the same to the next fraction so 6x1=6 which means your next fraction will be 6/24 so your 2 fractions right now are 4/24 and 6/24.
