Question

The product of two rational numbers is −36/49, if one of the number is 9/14, find the other.

Answer 1

Step-by-step explanation:

A centimorgan is a unit of measuring genetic linkage. It is defined as the distance between chromosome positions for which the expected average number of intervening chromosomal crossovers in a single generation is 0.01.

Answer 2

Answer:

Required value of other number is $( - 1 \frac{1}{7} )$

Step-by-step explanation:

Given,

product of two rational numbers is $- \frac{36}{49}$ and one number is $\frac{9}{14}$

Now we want to find another number.

Let the another number be x.

According to question,

$\frac{9}{14} \times x = - \frac{36}{49} \\ \frac{9x}{14} = - \frac{36}{49}$

By cross multiplication,

$9x \times 49 = - (14 \times 36) \\ x = - \frac{14 \times 36}{9 \times 49} \\ x = - \frac{2 \times 4}{7} \\ x = - \frac{8}{7} \\ x = - 1 \frac{1}{7}$

This is a problem of Algebra.

Some important Algebra formulas.

(a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab(a + b)

a³ - b³ = (a -b)³ + 3ab(a - b)

a² − b² = (a + b)(a − b)

a² + b² = (a + b)² − 2ab

a² + b² = (a − b)² + 2ab

a³ − b³ = (a − b)(a² + ab + b²)

a³ + b³ = (a + b)(a² − ab + b²)
