To divide by a fraction, multiply by its reciprocal. In this instance, 5/8 / 1/4 = 5/8 x 4 = 20/8 or 2 1/2.

The reciprocal of any number x is equal to 1/x. In this case, x = -2/7. Therefore the reciprocal of -2/7 is: 1/(-2/7) Now to simplify remember that when you divide by a fraction, it is the same as multiplying by the same number except with the numerator and denominator flipped. In this case: 1/(-2/7) = 1*(-7/2) = -7/2 or -3.5

A reciprocal is 1 divided by a number. So, the reciprocal of x is 1/x. For example: The reciprocal of 2 is 1/2 is 0.5 The reciprocal of 9 is 1/9 is 0.111111111111 The reciprocal of 0.5 is 1/0.5 is 2. To divide one by a number is called 'taking the reciprocal.' If you have a fraction, taking the reciprocal is fairly easy: simply 'flip' it. I.e., put the numerator in the denominator, and the denominator in the numerator. For example: The reciprocal of 2/3 is 3/2 The reciprocal of 7/8 is 8/7 The reciprocal of 1/4 is 4 (/1). The technical mathematical definition of the reciprocal of x is: "The number which, when multiplied by x, gives one."
