if you are 12-13 you will be in seventh grade and if you are 13-14 you will be eighth grade
The 9th grade is referred to as year 9 in England, and you are 13-14.
That would be a grade between 86% and 87%.
If by grade you mean percentage, you would have scored 67.5%. 40-13= 27 (27/40) * 100
13 ÷ 15 = 0.866666.... or 86 2/3 % which rounds to a grade of 87.
a 13 year old would normally be in 7th or 8th grade depending on whether or not they were born before September.
73% or C
To calculate your grade, divide the number of correct answers by the total number of questions. If you missed 3 out of 13 questions, you got 10 correct. Therefore, your grade would be 10/13, which is approximately 76.9%. Depending on the grading scale, this would typically be a C or C+.
I would think that she would be in the 7th or 8th grade because she just turned 13 years a few months ago.
13 - 4 = 9 correct 9/13 x 100 = 69% (rounded)
A 13 year old would normally be in either 7th or 8th grade. You normally start 7th grade at 12 and turn 13 during the school year or the summer after (depending on when your birthday is), so then the normal age for 8th grade is 13-14.
Usually, a child of the age of 12 years, should be either in the midst of 6th grade, and should turn of the year 13 in the middle of grade 7.
You use division. For example 13/47 is approximately 0.276 or 28%. 100-28 is 72 so the grade would be a 72.
