This is all really basic for alegbra, geometry and math in general. Here is what I got but remember to double check and work it out yourself to prove your answers and show your work so you can be credited for it. Please learn how to do it also so you will do well in the future good luck!

1. 1 4/9

Explanation: take the two and add them together to get 13/9 minus nine and get 4 left over therefore the answer is 1 4/9.

2. 1 3/7

Explanation: add the fractions to get 10/7 minus the seven to get 3/7 left over therefore answer is 1 3/7

3. 1 1/3

Explanation: add 7/12 + 7/12 + 1/12 + 1/12 (perimeter is all sides added) and get a total of 16/12 which simplifies to 4/3 which is 1 1/3

4. 8/21

Explanation: you have to get them to a common denomenator. So multiply 1/3 by 7 and get 7/21 and 2/7 by three to get 6/21. Then add together to get 13/21 and subtract 13 from 21 ro see the remaining portion.

5. 7 1/2 hours

Explanation: change all to a common denomenator of 4 then add all together to get 7 1/2.

6. 2 3/4%

Explanation: to subtract like this you have to first make a common denomenator of 4 and change the 8 1/2 to 7 6/4 then subtract the 5 3/4 to get 2 3/4.

7. .28

Explanation: move the decimal point to the left each time for every zero. two zeros, two times equals .28

8. 85.014

Explanation:Leave decimal point add a zero becuase nothing is in the tenths place and then write the one in the hundreths and the 4 in the thousandths place.

9. hundreths place

Explanation: The 8 is in the second spot after the decimal point which would be the hundreths place.

10. Five point five hundred and seventy nine thousandths

Explanation: you write the frist number then point where the decimal is and after that write it out according to order ending it with the last place given. In this case it’s the thousandths place.

Let me inform you what I do to remedy math issues in my head even quicker than with a calculator. First, I learn the solutions given you through so much and I do not feel their reply goes to be the pleasant one for you. Most persons propose finding out math, as with all different area, through rote – memorization and recessitation. The concern with finding out through rote is that you’re discouraged through making use of creativity whilst fixing issues. In different phrases, their is a couple of strategy to remedy a math concern and lecturers nowaday handiest educate scholars how one can study math in a single or 2 methods. The truth is that there are a number of methods to remedy math issues. For instance: One quantity minus one other quantity is solved through taking the highest quantity and subtracting the backside quantity. That works exceptional if the equation is 10 minus five. But whilst it’s five minus 10, you have got to take the closest quantity to the left, go it out, and lessen the importance through one whilst including a one to the importance to the proper. Then subtract the quantity to the proper once more. Hang on with me, ok? Most lecturers inform you that whilst you examine your subtraction, that you simply have got to cross by way of the concern two times to examine you reply they usually inform you that over and over and once more. But now do that: Add the quantity at the backside to the quantity at the reply. If you do it proper, you will have to get the quantity at the most sensible. That is anything that the majority lecturers do not educate you on account that this can be a ingenious reply. Rote goes over the equal concern two times to look if the reply is the equal. That is why and the way, through the years, I can do usual math in my head FASTER than a calculator. Good success to your experiences. Don
