Tom has 15 metersofwood he needs3/5 metersof wood for one shelf. How many shelves can he make

sashaice [31]

Answer:

25 shelves

Step-by-step explanation:

The number of shelves he can make is basically the total amount of wood he has divided by the amount of wood it takes per shelf.

Given in the problem:

Total Amount of Wood = 15 meters

Wood Amount needed per Shelf = 3/5

Hence,

Number of Shelves = 15 divided by 3/5

Note: dividing by a fraction means multiplying by its reciprocal (upside down version)

We show the division below:

Number of Shelves = $\frac{15}{\frac{3}{5}}\\=15*\frac{5}{3}\\=\frac{75}{3}\\=25$

So Tom can make 25 shelves
