Set up a proportion
3/7/12 = 1/x
3/7x = 12
x = 28
28 - 12 = 16
16 are left

Step-by-step explanation:
First find a common denominator, which is 8 & change all fractions to a denominator of 8
3/4 *(2/2) = 6/8
-5/8 + 6/8
1/8
Length of a wire = 23 cm
Given that :
▪︎The wire was cut into two pieces.
▪︎The longer piece of wire is 7 cm longer than the shorter piece of wire.
Let the shorter piece of wire be x.
Then, the longer piece of wire = x+7
An equation that can be derived from these statements :
▪︎x + x + 7 = 23
Let us solve this equation :
Thus, the value of x = 8.
Which means :
Length of the shorter piece of wire = 8 cm
Length of the longer piece of wire = 8 + 7 = 15 cm
Since the length of the two wires add up to form 23 cm(8+15=23), we can conclude that we have found out the correct measures of each wire.
Therefore, the length of the shorter piece of wire = <u>8 cm</u>
