2.3% of 100 is?
3.25% of 200 is?
4.19 divided by 28 is?
5.34 divided by 4 is?
6.W=5 P=10 && C=1

1. I don't understand #1.
2. 3% of 100
3% is the same as 3/100 (since percent means over 100)
3/100 is the same as 0.03
0.03 x 100= 3
So 3 is you answer
3. 25% of 200
25 is the same as 25/100 (or 1/4... either one really.)
25/100 (or 1/4) is the same as 0.25
0.25 x 200= 50
So 50 is your answer.
4. 19 divided by 28 is 2.375
(just use a calculater for that.)
5. 34 divided by 4 is 8.5
(also use a calculater.)
6. W=5, P=10, and C=1
part a:
W x C=
replace the letter with the numbers that they equal so it would be 5 x 1=
then just do basic math to get the answer.
5 x 1= 5
part b:
P x C + W x P divided by 7=
replace the numbers as you did in part A so it would be 10 x 1 + 5 x 10 divided by 7=
Then do order of operations (multiplication and division, then do addition and subtraction.)
10 x 1= 10 and 5 x 10= 50 so as of now the equation would be...
10 + 50 divided by 7=
50 divided by 7= 7.14
10 + 7.14= 17.14
So 17.14 is your answer.
