George is building a fence. He builds his fence at a constant rate of 1/3 section of fence every 1/2 hour. At this rate, which fraction represents the section of fence George can build per hour? Enter your answer as a fraction. (Type as a decimal, round to the hundredths place)

Answer:

Fraction of fence = 2/3 which is approximately 0.67

Explanation:

We know that he finishes 1/3 of the fence in 1/2 an hour. To know the fraction he can finish in one hour, we will simply use cross multiplication as follows:

1/3 of the fence ...................> 1/2 an hour

?? of the fence ....................> 1 hour

Fraction of the fence = (1/3 * 1) / (1/2)

Fraction of fence = 2/3 which is approximately 0.67

Hope this helps :)

Seven less than twice a number is 11. find the number

Seven less than twice a number is 11.

First, add seven to the end number 11.

11 + 7 = 18

Now, divide that by 2.

18 ÷ 2 = 9

And check it.

Twice the number 9 is 18. Seven less than that is 11.

The number is 9.

First, add seven to the end number 11.

11 + 7 = 18

Now, divide that by 2.

18 ÷ 2 = 9

And check it.

Twice the number 9 is 18. Seven less than that is 11.

The number is 9.

9: work backwards 11 + 7 = 18 , 18 divided by 2 + 9
