6 packages x 6 bookmarks in each one = 36 bookmarks
Q1. The answer is 53.33
<span>The initial </span>number is 100%. So, make a proportion:
If 8 is 15%, what number is 100%?
8 : 15% = x : 100%
15% * x = 8 * 100%
x = 8 * 100% / 15% = 53.33
Q2. The answer is 2.8425
The initial number 18.95 and it is 100%. How much is its 15%? Make a proportion:
If 18.95 is 100%, what number is 15% of it?
18.95 : 100% = x : 15%
x * 100% = 18.95 * 15%
x = 18.95 * 15% / 100% = 2.8425
Q3. The answer is 509.375%
The initial number is 64 and it is 100%. So, what percent is 326? Make a proportion:
If 64 is 100%, 326 is what percent?
64 : 100% = 326 : x
x * 64 = 326 * 100%
x = 326 * 100% / 64 = 509.375%
Q4. The answer is 400.
The initial number is 100%. Make a proportion:
If 40 is 10%, what number is 100%?
40 : 10% = x : 100%
x * 10% = 40 * 100%
x = 40 * 100% / 10%
x = 400
Answer:
3.6*10^3
Step-by-step explanation:
What is the quotient of 2.592× 10^7÷7.2×10^4
2.592× 10^7÷7.2×10^4
= (2.592/7.2)×10(7-4)
= 0.36*10^3
= 3.6*10^-1*10^4
= 3.6*10^(-1+4)
= 3.6*10^3
Hence the quotient expressed in scientific notation is 3.6*10^3
