Step-by-step explanation:
Given : Ashley recently opened a store that sells only natural ingredients. She wants to advertise her products by distributing bags of samples in her neighborhood. It takes one person 2 minutes to prepare one bag.
To find : How many hours will it take to prepare 900 bags of samples if Ashley and 5 of her friends do the work?
Solution :
Total number of people including Ashley are 6.
Number of bags to prepare is 900.
So, The number of bag per person is
bags per person.
Time taken by one person to prepare one bag is 2 minutes.
To prepare 150 bags time taken is
Converting minute into hours,
1 hour = 60 minutes
1 minute = hour
300 minute = hour
300 minute = 5 hour
Therefore, 5 hour will it take to prepare 900 bags of samples if Ashley and 5 of her friends do the work.

Step-by-step explanation:
When writing 1225 in scientific notation, it is convenient to choose an exponent so that the division result comes out with the right scale factor. It is easy to see that 1.2 < 1.6, so use of numbers with exactly one digit to the left of the decimal point would result in a fraction as an answer. We want the answer to have 1 digit left of the decimal point, so by scaling the operands to be 12. and 1.6, we get that result. Of course, the powers of 10 are adjusted accordingly.
This scaling process only matters if you're computing the results by hand. Any calculator can properly keep track of the required exponents.

"Back in the day" when slide rules were the calculating tool of choice, the operands and answer to any multiplication or division problem were only shown as 3 (sometimes 4) significant digits. All of the power-of-ten scaling was done "by hand" (usually, mentally). That is, the division would be 1225/1578 ≈ 776 × some scale factor. This is where thinking of the numbers as 12.25/1.578 = 7.76 comes in handy.
