The ratio of the length of haley's stick to the length of sarah's stick is 1 : 9. Sarah's stick measures 72 inches. how long is haley's stick?
1/9 = x/72
9x = 72
x = 72/9
x = 8
To find the length of Haley's stick, we first need to determine the ratio between the two sticks. According to the given information, the ratio is 1:9, which means that for every 1 unit of Haley's stick, Sarah's stick is 9 units.
Next, we need to find out the length of Haley's stick. We can do this by setting up a proportion using the ratio and the known length of Sarah's stick.
Let's assign a variable to the length of Haley's stick. We'll call it "x". The proportion can be set up as follows:
1 / 9 = x / 72
To solve for x, we can cross-multiply. Multiply 1 by 72 and 9 by x:
72 = 9x
To isolate x, divide both sides of the equation by 9:
72 / 9 = x
Simplifying the equation:
8 = x
Therefore, the length of Haley's stick is 8 inches.
