Question

От проволоки отрезали 3/4 что составило 15 см. Вычисли длину всей проволоки.

Answer 1

3/4=15cм,следоваетельно 15:3=5см, 5см*4(части)=20 см.  Ответ:20 см.

Answer 2

60 см потому что 4 части по 15 см,слаживаем их и получаем 60

Answer 3

Calculation of the Length of the Wire

To calculate the length of the entire wire, we need to determine the length of the portion that was cut off. According to the information provided, 3/4 of the wire was cut off, which measured 15 cm.

Let's calculate the length of the entire wire step by step:

1. Determine the length of the cut-off portion: - 3/4 of the wire = 15 cm - Let's denote the length of the entire wire as "x". - We can set up the following equation: (3/4)x = 15 cm.

2. Solve the equation for "x": - To find the value of "x," we can multiply both sides of the equation by (4/3) to isolate "x": - (4/3) * (3/4)x = (4/3) * 15 cm. - Simplifying the equation gives us: - x = 20 cm.

Therefore, the length of the entire wire is 20 cm.
