Question

50%, 25%, 20%, 10%, 1%
z liczby 1000
z liczby 280
z liczby 3400

Answer 1

A)

$50\%(1000) = 1000 \times ( \frac{50}{100} ) = 500 \\ \\ 25\%(1000) = 1000 \times ( \frac{25}{100} ) = 250 \\ \\ \\ 20\%(1000) = 1000 \times ( \frac{20}{100} ) = 200 \\ \\ \\ \\ \\ 10\%(1000) = 1000 \times ( \frac{10}{100} ) = 100 \\ \\ \\ \\ \\ \\ 1\%(1000) = 1000 \times ( \frac{1}{100} ) = 10$

В)

$50\%(280) = 280 \times ( \frac{50}{100} ) = 140 \\ \\ 25\%(280) = 280 \times ( \frac{25}{100} ) = 70 \\ \\ 20\%(280) = 280 \times ( \frac{20}{100} ) = 56 \\ \\ 10\%(280) = 280 \times ( \frac{10}{100}) = 28 \\ \\ \\ 1\%(280) = 280 \times ( \frac{1}{100} ) = 2.80$

С)

50%(3400)=3400×(50/100)=1700

25%(3400)=3400×(25/100)=850

20%(3400)=3400×(20/100)=680

10%(3400)=3400×(10/100)=340

1%(3400)=3400×(1/100)=34
