Martin uses 3/5 yard of fabric to make 1 backpack. How many backpacks can Marti make if he has a total of 9 yards of fabric?
To make 1 backpack, Martin uses 3/5 yard of fabric.
If Martin has 9 yards of fabric, he can make 9/(3/5) = 9 * 5/3 = 15 backpacks. Answer: \boxed{15}.
To find out how many backpacks Martin can make, divide the total fabric he has (9 yards) by the amount of fabric used for each backpack (3/5 yard).
9 yards ÷ (3/5 yard) = 9 yards × (5/3 yard)
Now, let's simplify the equation:
= 45/3
= 15
Therefore, Martin can make 15 backpacks if he has a total of 9 yards of fabric.
To solve this problem, we need to find out how many times 3/5 yard can fit into 9 yards of fabric.
First, we need to calculate how many times 1 yard can fit into 9 yards:
9 yards ÷ 1 yard = 9
Now, let's calculate how many times 3/5 yard can fit into 1 yard:
1 yard ÷ 3/5 yard = 1 yard × 5/3 yard = 5/3
Finally, we can multiply the number of times 3/5 yard can fit into 9 yards by the number of times 1 yard fits into 9 yards to find the number of backpacks Martin can make:
9 × 5/3 = 45/3 = 15 backpacks
Therefore, Martin can make 15 backpacks if he has 9 yards of fabric.
