5. A) What is 20% of 156?
B) 30 is 29% of what number?
C) 44 is what percent of 62?
D) 55% of 26 is what number?
A) P/T = ?/156 = 20/100
20/100= 0.2
0.2x156=31.2
P/T = 31.2/156 = 20/100
B) P/T = ?/30 = 29/100
29/100=0.29
0.29x30=8.7
P/T=8.7/30=29/100
C) P/T = 44/62 = ?/100
44/62=0.7
0.7x100=70
44/62 = 70%/100%
D) P/T = ?/26 = 55%/100%
55/10=5.5
26/10=2.6
2.6x5.5=14.3
P/T = 14.3/26 = 55%/100%

Good job! Keep up the good work! But I think letter B is wrong.
Your mistake was:
You thought that 30 is the total. 30 is the part of an unknown number. Okay?
Correct answer:
29% divided by 29% = 1%
30 divided by 29 = 1.034
1.034 x 100 = 103.4
Answer: 103.4
Double check:
0.29 ---> decimal for 29%
103.4 x 0.29 = 29.986 or
30(rounded)
30 is the part
The total is 103.4
Just remember:
