This week, Ariel ended up needing 12 gallons of gas. That is 20% more than she needed last
Jobisdone [24]

Answer:

10 gallons

Step-by-step explanation:

She used 12 gallons this week and used 20% more than last week. That means 12 gallons is 120% of last weeks gas. Since 12 times 10 equals 120, then to find 20% you do 20 divided 10 and subtract the answer from 12.

20% is 2 because 20 divided by 10 is 2. 12 minus 2 is 10

Hope this helps :)

Is it true that the order when dividing three real numbers does not effect the answer?
Diano4ka-milaya [45]

When dividing three real numbers the order can effect the answer.

Example:

8:4:2

1. 8:4:2=(8:4):2=2:2=1;

2. 8:4:2=8:(4:2)=8:2=4.

As you can see the results are different.

Answer: It is not true.
