Question

Число яблонь в саду относится к числу груш как 2к5 определите сколько ябонь и груш ростет в саду , если яболнь на48 меньше чем груш

Answer 1

Так как число яблонь относится к числу груш как 2 к 5, то если принять число яблонь за 2х, число груш будет 5х. Яблонь на 48 меньше, чем груш, т.е. 5х-2х=48
3х=48
х=48:3
х=16
16*2=32 яблони в саду.
16*5=80 груш в саду.

Answer 2

Solving the Problem

To solve this problem, we can use algebra to represent the relationship between the number of apple trees and pear trees in the garden. Let's denote the number of apple trees as A and the number of pear trees as P. We are given that the ratio of apple trees to pear trees is 2:5 and that there are 48 fewer apple trees than pear trees.

Setting Up the Equations

We can set up the following equations based on the given information: 1. The ratio of apple trees to pear trees: A/P = 2/5 2. The difference between the number of apple trees and pear trees: P - A = 48

Solving for the Number of Trees

We can solve these equations simultaneously to find the values of A and P.

Solution

Using the given information and the equations, we can solve for the number of apple trees and pear trees in the garden.

Let's denote the number of apple trees as A and the number of pear trees as P.

From the given ratio, we have: A/P = 2/5 [[1]]

And from the given difference, we have: P - A = 48 [[2]]

Solving the Equations

We can solve the second equation for P: P = A + 48

Substitute this value of P into the first equation: A / (A + 48) = 2/5

Cross-multiply to solve for A: 5A = 2(A + 48)

Solving for A: 5A = 2A + 96 3A = 96 A = 32

Now that we have the value of A, we can find the value of P: P = A + 48 P = 32 + 48 P = 80

Conclusion

Therefore, there are 32 apple trees and 80 pear trees growing in the garden.
