lisa's dog has 4 squeaky toys. two thirds of the dog's toys are squeaky toys. how many dog toys does lisa's dog have in all?
(2/3)x = 4
x = 4 / (2/3)
x = 4 * (3/2)
x = 12/2 = 6
can you explain it for 3rd grade? don't understand what X is?
x represents the total number of toys.
The equation means 2/3 of some number is 4.
How did your teacher show you how to solve this kind of problem?
My teacher showed me in a way from like a few weeks ago. I almost don't remember. I
saw from other part of my homework but they were unit fractions. The questions are high level because they are Enrich level. So its kind of hard.
So then how can i draw it in a picture?
You could use an equivalent fraction.
2/3 = 4/6
Draw a rectangle with six equal boxes. Color 4 of these boxes.
So then 4/6 is the answer! if it is i guess thnx! Im only 8 so... its hard.
4 divided by 2/3
4
_______
2/3
Rewrite so you can see it better. 4 over 1 divided by 2 over 3.
4 2
___ / ____ =
1 3
Take the reciprocal 2/3
4 3 12
___ x _____ = ______ = 6
1 2 2
Answer: 6
Check:
2/3 of 6
2 6 12
__ x ___ = ___ = 4
3 1 3
To solve this problem, we need to find the total number of toys that Lisa's dog has. We know that two-thirds of the toys are squeaky toys, and specifically, four of them are squeaky toys.
Let's denote the total number of toys as "x". According to the given information, two-thirds of x is equal to 4. We can represent this equation mathematically:
(2/3) * x = 4
To solve for x, we need to isolate it on one side of the equation. To do this, we can multiply both sides of the equation by 3/2 (the reciprocal of 2/3).
(3/2) * (2/3) * x = (3/2) * 4
The 2/3 cancels out on the left side, leaving us with:
x = 6
Therefore, Lisa's dog has a total of 6 toys in all.
