Tristan has a pickup truck that could carry 3/5

​-cord of firewood. Find the number of trips needed to carry 6 cords of wood.

To find the number of trips needed to carry 6 cords of wood, we need to divide the total amount of wood by the carrying capacity of Tristan's pickup truck.

Let's calculate it step by step:

Number of cords of wood Tristan's pickup truck can carry = 3/5
Number of trips needed to carry 6 cords of wood = 6 / (3/5)

To divide a number by a fraction, we need to multiply by its reciprocal:
6 / (3/5) = 6 * (5/3)

Calculating the expression:

6 * (5/3) = 30/3 = 10

Therefore, Tristan would need to make 10 trips to carry 6 cords of wood.

To find the number of trips needed to carry 6 cords of wood in Tristan's pickup truck, we can set up a proportion.

Let's say x represents the number of trips needed. Since Tristan's pickup truck can carry 3/5 of a cord of firewood in one trip, the proportion can be set up as:

(3/5) / 1 = 6 / x

To solve for x (the number of trips), we need to cross-multiply and then divide:

(3/5) * x = 6 * 1

Now we can simplify the equation:

(3x) / 5 = 6

Next, we can multiply both sides of the equation by 5 to eliminate the denominator:

3x = 6 * 5

Simplifying further:

3x = 30

Finally, divide both sides of the equation by 3 to solve for x:

x = 30 / 3

x = 10

Therefore, Tristan would need to make 10 trips to carry 6 cords of wood in his pickup truck.
