Find each value of n.

1) 10 out of 28 = n out of 56 ______

2) n out of 55 = 7 out of 11 _____

3)Tina has 400 stickers and Jan has 300 stickers. If 25% of each girl's collection is heart stickers, how many heart stickers does each girl have?

4) Tina has 140 smiley face stickers and Jan has 120. Who has the greater percentage of smiley face stickers? What is the percentage?

Answer 1

1) 10/28=n/56
56x10=28xn (cross cancel)
560=28n
n=20

2) n/55=7/11
55x7=nx11
385=11n
n=35

3) 400 x .25=100
300 x .25=75
100+75=175

4) 140/400=.35=35% (Tina)
120/300=.40=40% (Jan)
40% is more than 35%, so Jan has the greater percentage (40%)

Answer 2

1. 10/28=n/56
28n=560
n=20

2. n/55=7/11
11n=385
n=385/11
n=35

3. Tina 400 x 25%= 100
Jan 300 x 25%= 75

4. Tina 140/400=35%
Jan 120/300=40%
answer: Jan

sorry, doing someone else's homework is usually against my ethical behaviour, but this was just too easy....

seriously, you should be worried that you can't do this :S

Answer 5

20

35

a)300 = 75 heart stickers
b) 400 = 100 heart stickers

Jan has the higher percentage... she has 40%
Tina has 35%

Answer 6

This is basic math. You shouldn't be asking someone on here to do your homework for you when you could simply spend 5 minutes doing it yourself.

Sorry, but if you get people to do your work for you now, you will find it really tough later in life.
