To convert (a grade) out of (a potential) into (something) out of 100 multiply (a grade) by 100 and divide the result by(a potential) So that 45 out of 50 = (45 x 100) ÷ 50 = 4500 ÷ 50 = 90% or 21 out of 30 = (21 x 100) ÷ 30 = 2100 ÷ 30 = 70%
65/100
63% or D
When you get 19 out of 30 questions right in the sixth grade," that means that you need to get you grade or score up to @ least 27-28 out of 30 correct." If you have any other questions, please email me at : kianabrown9@aol.com.
well each question is worth 3.3333333 points so multiply how many you got right by 3.333333 and that's your grade
21 - thirty minus nine is 21.

No.(20)2 = 400(21)2 = 441(20)2 + (21)2 = 881(30)2 = 900(20)2 + (21)2 is not equal to (30)2
Let's lay out the known information in equations, where B is the number of boys and G is the number of girls. Then we express the number B in terms of G, which is twice as much less 12, or (2G-12) B + G = 51 , and B = 2G - 12 Now, replace the B in the first equation with its value from the second equation (2G - 12) + G = 51 Remove the brackets 2G - 12 + G = 51 Add 12 to both sides 2G + G = 51 + 12 3G = 63 Divide both sides by 3 G = 21 Now, to check if we're right, Replace G in the first equation B + 21 = 51 B = 30 If that's right then 30 = 2(21) - 12 30 = 42 - 12 And it is, so we know that there are 21 girls and 30 boys in ninth grade.
