Question

В мотке было 117 м проволоки. Для соединения столбов электропередачи отрезали третью часть проволоки . Сколько метров проволоки осталось в мотке?

Answer 1

1) 117: 3=39(м) ушло на соединение электропередач
2) 117-39=78(м) осталось
Ответ: осталось 78 м проволоки.

Answer 2

Calculating Remaining Wire in the Coil

To calculate the remaining wire in the coil, we can use the following steps:

1. Initial Length of Wire in the Coil: The initial length of wire in the coil is 117 meters. 2. Fraction of Wire Used: A third of the wire was used to connect the transmission poles.

Calculation

To find the remaining length of wire in the coil, we can use the following calculation:

117 meters (initial length) - (1/3 * 117 meters) = 78 meters

So, there are 78 meters of wire remaining in the coil.
