You practice your basketball shots every day. On Friday you made 20 shots. On Saturday you made 16 shots. What is the percent decrease in shots you made?4%


16%


20%


80%

Answers

Answer 1
Answer: So,

All you have to do to find the percent decrease is to subtract your score on Saturday from your score on Friday and divide the result by your score on Friday.  If you let "f" represent your score on Friday and let "s" represent your score on Saturday, you can re-write this mathematically:

(f - s)/(f) = percent\ decrease

Substitute.
(20 - 16)/(20) = percent\ decrease
(4)/(20) \ or\ (1)/(5)\ or\ twenty\ percent = percent\ decrease

The percent decrease in shots you made was 20%.  That would be option C.
Answer 2
Answer:

the percent decrease was 20% because 4 shots less were on sat.

put it into a fraction to find the percentage:

4/20

=20%

Please could someone help me work out 2/3 of 8

Answers

'of' in mathematics means multiplication

(2)/(3) * 8 = (16)/(3) = \boxed{\bf{5(1)/(3)=5.\overline{33}}}
You would divide 8 into 3.
Then multiply that by two.
That will be your answer to 2/3 of 8!
