Question

Задача Для школы купили 5 мотков электрического провода по 56 метров в каждом. Израсходовали две седьмых части всего провода.Сколько метров провода осталось?

Answer 1

5*56= 280 метров купили
280:7*2 = 80 метров потратили
280-80= 200 метров осталось
ОТвет 200 метров

Answer 2

$5*56=280 \\ 280:2/7=80 \\ 280-80=200$

Answer 3

Calculating Remaining Length of Wire

To calculate the remaining length of wire, we can follow these steps:

1. Total Length of Wire: The total length of wire purchased is 5 motkov * 56 meters = 280 meters. 2. Length Used: Two sevenths of the total wire has been used. 3. Remaining Length: We can calculate the remaining length using the formula: Total Length - Length Used.

Calculation

The calculation for the remaining length of wire is as follows: - Total Length of Wire = 280 meters - Length Used = 280 * 2 / 7 = 80 meters - Remaining Length = 280 - 80 = 200 meters

The remaining length of the wire is 200 meters.
