Kevalaih Saptakam Gunyat:

*For 7 the Multiplicand is 143*
Kevalaih Saptakam Gunyat is the corollary to

Paraavartya Yojayet, the fourth

sutra of

Vedic mathematics.

This sutra converts

fractions in which the

denominator is 7 to a

decimal. It is used in conjunction with

Ekanyunena Purvena. This will not arrive at every possible decimal point in every case.

**Example: convert 1/7 to a decimal**
We multiply the

multiplicand (143) by 999 using

Ekanyunena Purvena. We use 999 because it has the same number of digits as our multiplicand and consists only of nines

143 x 999 =

**142857**
Multiply that number by the

numerator: 1 x 142857 = 142857

Place a decimal point at the beginning: 0.142857

Thus, 1/7 = 0.142857

**Example: convert 2/7 to a decimal**
We multiply the

multiplicand (143) by 999 using

Ekanyunena Purvena.

143 x 999 =

**142857**
Multiply that number by the

numerator: 2 x 142857 = 285714

Place a decimal point at the beginning: 0.285714

Thus, 2/7 = 0.285714
