One wire is 15 meters long, and the rest is just 4 meters long. How many parts of the total length of this wire have been used?
15÷(15+4)=15/19
15 / 19 of the total length
A wire is 5 meters long. If 2-5 meters is used, how many parts of the total length are left? How many meters are left?
The length of the wire is 5 meters. If 2-5 meters is used, how many parts of the total length are left? How many meters are left?
5 - (5 * 2 / 5) = 3, leaving 3 / 5 of the total length
Three meters left
Two fifths of the total length of a wire is used, and how many fifths of the total length are left
2 out of 1-5 = 3 out of 5
