Answer:
33.3%
Step-by-step explanation:
The number of people that must be fed has increased from 4 to 6, so is 6/4 = 3/2 as many as planned.
Assuming the additional people eat the food at the same rate as the original people, the time and number of people are assumed to be inversely proportional. That is, the time the food will last is 2/3 of the originally expected time. It has decreased by 1/3 × 100% = 33.3%.
___
If you like, you can count rations. For four people for 12 days, at 3 rations per person per day, a total of 144 rations are needed. When the number of people becomes 6, the number of days that will last is ,,,
(144 rations)/(6 persons)/(3 rations/person/day) = 8 days
The percentage change in trip days is ...
(8 -12)/12 × 100% = -4/12 × 100% = -33.3% . . . a decrease of 33.3%

Answer:
90
Step-by-step explanation:
If you add all those together than you get 89.6 which equals to 90 if estimating. no need for an explanation
Only add those numbers up and round
For this case we have the following expression:
We note that, we have a 4-digit number divided by a number of 1 digit other than 1.
Therefore, the answer must be at least 3 digits.
Thus, the first number of the quotient is located in hundreds place.
To verify this answer, we make the division with a calculator:
We observe that indeed, the first number of the quotient is located in hundreds place.
