Question

A farm has 15 rows of fruit trees with 7 trees in each row. The last 4 rows of trees are cherry trees. The remaining trees are orange trees. How many orange trees are on the farm?​

Answer 1

To find the number of orange trees on the farm, we first need to determine the total number of trees in the last 4 rows, which are cherry trees.

Given that there are 15 rows of fruit trees with 7 trees in each row, we can calculate the total number of trees on the farm by multiplying the number of rows by the number of trees in each row: 15 rows * 7 trees = 105 trees.

Since the last 4 rows are cherry trees, we can calculate the total number of cherry trees by multiplying the number of cherry tree rows by the number of trees in each row: 4 rows * 7 trees = 28 cherry trees.

To find the number of orange trees on the farm, we subtract the number of cherry trees from the total number of trees: 105 trees - 28 cherry trees = 77 orange trees.

Therefore, there are 77 orange trees on the farm.

Answer 2

77 oranges tree

Explanation:

The farm has a total of 15 rows of fruit trees, and each row contains 7 trees.

In order to find the total number of trees, we can multiply the number of rows by the number of trees in each row:

`\sf \textsf{Total trees = Number of rows }* \textsf{ Number of trees per row}`

`\sf \textsf{ Total trees = 15 rows }*\textsf{ 7 trees/row}`

`\sf \textsf{ Total trees = 105 trees}`

Now, we mentioned that the last 4 rows are cherry trees.

Since each row contains 7 trees, the total number of cherry trees is:

`\sf \textsf{Cherry trees = 4 rows }* \textsf{ 7 trees/row}`

`\textsf{ Cherry trees = 28 trees}`

Now, to find the number of orange trees, subtract the number of cherry trees from the total number of trees:

`\textsf{ Orange trees = Total trees - Cherry trees}`

`\textsf{Orange trees = 105 trees - 28 trees}`

`\sf \textsf{Orange trees = 77 trees}`

So, there are 77 orange trees on the farm.
