Answer:
For the first one, shade in 1 circle at the start
Then shade in 9/4 more, so you would fully shade 2 more because every 4 equals 1.
Then shade 1 quarter of the next circle, or 1 of the 4 portions of the next circle.

For the second one, shade in 2 circles at the start
Then shade 8/5 more, so fully shade one more because every 5 numbers equals one shaded circle.
Then shade 3/5 of the next circle. So you would shade 3 of the 5 portions of the circle
