Lisa has 12 more stickers than John, and together they have 60 stickers. What is the ratio of the number of Lisa’s stickers to the number of John’s stickers?

x + x + 12 = 60

2x = 48
x = 24

John has 24 stickers
Lisa has 36 stickers

36/24 = 3/2

Roy had 3 times as many strickers as Sam.After Sam had bought another 60 strickers he had twice as many strickers as Roy.How many strickers did Sam have at first?

Let's first find out how many stickers John has. If we let x represent the number of stickers John has, then we can express Lisa's number of stickers as x + 12 (since Lisa has 12 more stickers than John).

Since together they have 60 stickers, we can write the following equation:

x + (x + 12) = 60

Simplifying the equation:

2x + 12 = 60

Subtracting 12 from both sides:

2x = 48

Dividing both sides by 2:

x = 24

So, John has 24 stickers.

Now, we can calculate Lisa's number of stickers:

x + 12 = 24 + 12 = 36

Therefore, Lisa has 36 stickers.

The ratio of the number of Lisa's stickers to the number of John's stickers is 36:24, which can be simplified to 3:2.

To solve this problem, we need to understand the given information.

First, let's assign variables to the number of stickers Lisa and John have. Let's say the number of stickers Lisa has is L, and the number of stickers John has is J.

From the problem, we know that Lisa has 12 more stickers than John, so we can express this as an equation: L = J + 12.

We also know that together they have 60 stickers, so we can write another equation: L + J = 60.

Now we have a system of two equations with two variables:

L = J + 12 (equation 1)
L + J = 60 (equation 2)

To solve this system, we can use substitution or elimination method.

Let's use the substitution method to solve this system:

From equation 1, we can rewrite it as J = L - 12.

Now we can substitute this expression for J in equation 2:

L + (L - 12) = 60.

Simplifying this equation, we get:

2L - 12 = 60.

Adding 12 to both sides of the equation, we get:

2L = 72.

Dividing both sides by 2, we find:

L = 36.

Now that we have the number of stickers Lisa has, we can substitute this value back into equation 1 to find the number of stickers John has:

J = 36 - 12 = 24.

Therefore, Lisa has 36 stickers and John has 24 stickers.

The ratio of the number of Lisa's stickers to the number of John's stickers is:

36:24

Simplifying this ratio, we get:

3:2

So, the ratio of the number of Lisa's stickers to the number of John's stickers is 3:2.
