c - 9/10 = 1/3
c= 1 1/15?
You're close -- but it's not right.
1 1/2?
nvm that's not right
Aly, you have to add 9/10 to both sides. Your answer would be 9/10+1/3. Change both denominators to 30.
To solve the equation c - 9/10 = 1/3, you need to isolate the variable c on one side of the equation. Here's how you can do it:
First, let's get rid of the fraction on both sides of the equation by multiplying every term by the common denominator, which is 30. Since the denominator of 9/10 is 10 and the denominator of 1/3 is 3, we can multiply both fractions by 30 to eliminate the denominators:
30 * (c - 9/10) = 30 * (1/3)
Expanding the equation gives us:
30c - 27 = 10
Next, let's isolate the c-term by moving the constant term (-27) to the other side of the equation. We can do this by adding 27 to both sides:
30c - 27 + 27 = 10 + 27
This simplifies to:
30c = 37
Lastly, divide both sides of the equation by 30 to solve for c:
(30c) / 30 = 37 / 30
The result is:
c = 37/30
To express this as a mixed number, divide the numerator (37) by the denominator (30). The quotient is 1, and the remainder is 7. Therefore, the mixed number is:
c = 1 7/30.
So, the correct answer is c = 1 7/30, not c = 1 1/15.
