I can help you with #20. For example, lets say 3/5, this fraction would be made up of 5 parts and 3 are covered, which doesn't make it full, if it was 5/5 it would be full. When you do something with a reciprocal you turn it over, so 3/5 would be turned over to 5/3, thus making it a whole number
Answer:
- 1/8
Step-by-step explanation:
5/8 - 6/8
Just consider the numerators (exclude the 8's),
5 - 6 = -1
Now substitute it with the same denominator 8.
-1/8
now, he had 3200, he took 1500 for deposit, so, 3200 - 1500, he had left in his pocket 1700.
so after 5 years, he'll have 1700 + 1800.
It would be the Ys in the points, the second numbers: 0,-3,-9,5,7
