Step-by-step explanation:
3/8 = 0.375
5/8 = 0.625
4.375 - 1.625
= 2.75
Answer:
she didnt go back from 15 she went back from 20and the arrows should be going backwords not forwards
16/20. We reduce that and get 4/5.
After this it's much simpler to chage it.
100 dividied by 5 is 20. (20,40,60,80,100)
So the 4th number (4/100)
is 80. 80%.
20% she didn't and 80% she did :) (100-80)
3×6/8 reduce is 3× 3/4= 3/1×3/4=9/4 or 2 1/4
Answer:
218
Step-by-step explanation:
first find the area of the circle-

to find the area of the triangle, we need the base and the height. The base we know is 16, since we don't know the height yet, use the Pythagorean theorem to find the height. One leg is 16 the hypotenuse is 20 (2* the radius).

Now I know the height is 12. Find the area of the triangle

subtract the area of the triangle from the area of the circle
314-96=218
