Answer:2/6, 7/21, 15/45
Step-by-step explanation:
So we know that 6,21,45 are all multiples of 3
To find the numerator we have to divide each multiple by 3
so for the first one it would be 6/3 which is 2. So 2 is the numerator and the answer for the first one is 2/6
now we have to do the same method for the next fraction so we do 21/3=7
so the numerator is 7 and the fraction is 7/21
now for the last one we have to do the same method again
45/3=15 so the numerator is 15 and the answer is 15/45
You can use this method for any question like this
so the final answers are 1/3=2/6=7/21=15/45
Hope this helps
