Find the reciprocal of each number 2/3, 1/7, 4 ( show work)

help

Step-by-step explanation:

A reciprocal is the fraction flipped around. So basically 3/2, 7/1, and 1/4. Since 4 is a whole number the denominator is 1. Therefore, the reciprocal is 1/4.

-4/7 =n

Step-by-step explanation:

2/3 ( 1+n) = -1/2 n

Multiply each side by 6 to get rid of the fractions

6*2/3 ( 1+n) =6* -1/2 n

4(1+n) = -3n

Distribute

4+4n = -3n

Subtract 4n from each side

4+4n -4n = -3n -4n

4 = -7n

Divide each side by -7

4/ -7 = -7n/-7

-4/7 =n
