So, you know that Shaya saw 10 birds, and Vikram saw 1 less than 4/5 of that, you know that you need to find out 4/5 of 10. Well, if you make both numbers a fraction and get an equal denominator you get: (4/5 and 10/1, or in other words 8/10 and 10.) You now know that 4/5 of 10 is 8, and 1 less than 8 is seven. So, the final answer is seven.
