Question

The product of two no.is -7/16 if one of them is 4/5 find other

Answer 1

Let the unknown number be x

Known number = 4/5

Product of two numbers = -7/16

4/5 * x = -7/16

4x/5 = -7/16

4x = (-17/16) * 5

4x = -85/16

x = -85/(16 * 4)

x = - 85/64

Therefore the another number is -85/16.
