At Mariah's birthday party, 9 of her friends ate 3/4
of her chocolate cake. How much of the cake did each friend eat?(1 point)
of her chocolate cake. How much of the cake did each friend eat?(1 point)
To find out how much of the cake each friend ate, we need to divide the total amount eaten by the number of friends.
Since 9 friends ate 3/4 of the cake, we can calculate how much each friend ate by dividing 3/4 by 9:
(3/4) / 9 = 3/4 * 1/9 = 3/36
Simplifying 3/36, we get:
1/12
Therefore, each friend ate 1/12 of the cake.
Since 9 friends ate 3/4 of the cake, we can calculate how much each friend ate by dividing 3/4 by 9:
(3/4) / 9 = 3/4 * 1/9 = 3/36
Simplifying 3/36, we get:
1/12
Therefore, each friend ate 1/12 of the cake.
The product of 9 and the sum of a number and 8 is 180. What is the number?
Let's denote the number we are trying to find as "x".
The given equation is: 9(x + 8) = 180
First, we distribute 9 to both terms inside the parentheses:
9x + 72 = 180
Next, we subtract 72 from both sides to isolate the x term:
9x = 180 - 72
9x = 108
Finally, we divide both sides by 9 to solve for x:
x = 108 / 9
x = 12
Therefore, the number is 12.
The given equation is: 9(x + 8) = 180
First, we distribute 9 to both terms inside the parentheses:
9x + 72 = 180
Next, we subtract 72 from both sides to isolate the x term:
9x = 180 - 72
9x = 108
Finally, we divide both sides by 9 to solve for x:
x = 108 / 9
x = 12
Therefore, the number is 12.
