Answer:

15m + 11n

Step-by-step explanation:

(12m+4n)+(3m+7n) is the same as 15m+11n because all that happened was the combination of like terms.

12m + 3m = 15m

4n + 7n = 11n

(12m+4n)+(3m+7n) = 15m+11n

11/21 as a decimal and a percent
pochemuha

11/21 written as a decimal would be 0.52381 and in percent, it would be 52.381%.

To solve percent, since the total or 1/1 is 100%, we have to remember that the answer is less than 100%. So, we move 2 decimal places right to make it into percent. Then, the answer is 52.381.

To solve percent, you would do 100/21. Then, you would get 4.7619047619. You multiply that by 11 and get 52.381. But, you have to move 2 places left since fractions are tens, hundreds. So, you would get 0.52381.
