Question

Сумма двух чисел составляет 180% первого слагаемого.На сколько % первое слагаемое больше второго?

Answer 1

пусть числа a и b.

a+b=180%a=1,8a, b=0,8a, a=1,25b, т.е. a больше b на 25%

Answer 2

Answer in detail. The sum of two numbers is 180% of the first addend. By how much% is the first addend greater than the second?

Let the first addend be x and the second addend be y. Then, according to the given condition, we have:

x + y = 1.8x

Solving for y, we get:

y = 1.8x - x

y = 0.8x

Dividing both sides by x, we get:

y/x = 0.8

Multiplying both sides by 100, we get:

(y/x) * 100 = 80

This means that the second addend is 80% of the first addend. Therefore, the first addend is 20% greater than the second addend.
