So 60% of the class are boys, but we're given the number of girl students. We know that the remaining 40% of the class are girls, which equals 12 students. To find out the total number of students in the class we can divide the number we're given into 10%, which we can then multiply to give 100%.
So 40% of the class equals 12 students, we divide by 4 to give 10%, so 12 ÷ 4 = 3. So 10% of the total class is 3 students, we times by 10 to find 100% of the class, so 3 x 10 = 30 students.
Answer:
Step-by-step explanation:
25 = 5 * 5
36 = 2*2*3*3
117 = 3*3*13
3825 = 5*5*3*3*17

so think of it as a interger
<u>Answer:</u>
2.06 hours
<u>Step-by-step explanation:</u>
Money saved by Jordan to buy a $80 video game = × =
So Jordon needs 80 - 64 = $16 more to get the video game
He gets $7.75 per hour by working, so assuming the number of hours to be x he needs to work to get $16, we can write it as:
Therefore, Jordan needs to work at least for 2.06 hours to save the rest of the money for the video game.
