Sam has 9 yellow pencils in his desk. 3/4 of his pencils are yellow. How many pencils does Sam have in his desk?
3rd grade fraction, slightly confusing to me
thank you very much
You're very welcome.
how do I solve for X? can you show me how?
Divide both sides of the equation by 3/4.
3/4x = 9
x = 9/(3/4)
x = 9 * (4/3)
x = 36 / 3 = 12
To solve this problem, we need to find out how many pencils Sam has in total, given that 3/4 of them are yellow.
In this case, we know that 3/4 of Sam's pencils are yellow, and that there are 9 yellow pencils. Let's use a fraction to represent all the pencils.
If 3/4 of the pencils represent 9 yellow pencils, we can write it as:
3/4 * Total pencils = 9 yellow pencils
To solve for the total number of pencils, we need to isolate the variable. We can start by multiplying both sides of the equation by the reciprocal of 3/4, which is 4/3. This cancels out the fraction on the left side:
(3/4 * Total pencils) * (4/3) = (9 yellow pencils) * (4/3)
Simplifying the equation on both sides, we have:
Total pencils = (9 * 4) / 3
Total pencils = 36 / 3
Total pencils = 12
Therefore, Sam has a total of 12 pencils in his desk.
Let x = total pencils
3/4x = 9
Solve for x.
