20/10 as a mixed number

Answers

20/10 as a mixed number:

20 ÷ 10 = 2.

10 goes into 20 two times. So 20/10 as a mixed number is a whole number: 2. 

20/10 = 2

First, decide how many times 10 can go into 20. 10 can "fit in" to 20 exactly 2 times. Since there is nothing left over, the "mixed number" is simply 2. 
Another way to do this is to just divide the top by bottom, since it will divide evenly. 
20/10 = 2.
Answer: 2

What temperature is 10 degrees higher than -22 degree celsius?

Answers


Higher = warmer

Lower = colder

Therefore, what temperature is 10 degrees higher than -22 degrees Celsius is -12 degrees celsius

If the temperature is -22 then you add 10 degrees so the answer is -12. When you add a temperature that is negative, you go up you don't just do -22+10=-32 because that's going down and that's a common mistake!Hope it helps!!!
