Question

на лесной поляне собрались 28 стрекоз,а бабочек --в 3 раза больше,чем стрекоз.Число бабочек и стрекоз вместе составило 8% числа муровьё. Сколько всего насекомыхна этой поляне?

Answer 1

1)28*3=84(насек.)-стрекоз было на поляне

2)28+84=112(насек.)-бабочек и стрекоз было на поляне

3)112:8*100=1400(насек.)-муравьёв было на поляне

4)112+1400=1512(насек.)-всего было на поляне

Ответ: 1512 насекомых

Answer 2

28*3=84(бабочки) на поляне

28+84=112 (бабочек и стрекоз на поляне)

112\8*100=1400(муравьёв)

1400+84+28=1512(насекомых на поляне)

                    Ответ:1512 насекомых на поляне! =)

Answer 3

Calculation of the Total Number of Insects on the Meadow

To find the total number of insects on the meadow, we need to determine the number of dragonflies and butterflies separately and then add them together.

Given information: - Number of dragonflies: 28 - Number of butterflies: 3 times the number of dragonflies (84, since 28 * 3 = 84) - The total number of dragonflies and butterflies combined is 8% of the number of ants on the meadow.

Let's calculate the total number of insects step by step:

1. Calculate the total number of ants on the meadow: - The total number of dragonflies and butterflies combined is 8% of the number of ants. - Let's assume the total number of ants is represented by 'x'. - 8% of 'x' is equal to the sum of dragonflies and butterflies: 28 + 84 = 112. - Mathematically, this can be represented as: 0.08 * x = 112.

2. Solve the equation to find the total number of ants: - Divide both sides of the equation by 0.08: x = 112 / 0.08. - Calculating this, we find that the total number of ants on the meadow is 1400.

3. Calculate the total number of insects on the meadow: - The total number of insects is the sum of dragonflies and butterflies: 28 + 84 = 112.

Therefore, the total number of insects on the meadow is 112.
