What is the converse of the following conditional statement? If x = –10, then x2 = 100

tangare [24]

The converse would be If x² = 100 then x = -10

So essentially if the conditional statement is p → q then the converse is q → p (In essence, the converse of a conditional statement is formed by interchanging the hypothesis and the conclusion.)

Rename 5/6 and 14/15 using the least common denominator.

baherus [9]

Answer:

$\frac{25}{30}~and~\frac{28}{30}$

Multiply 5 by 5 to get your first parameter.

$5 * 5 = 25$

Multiply 6 by 5 to get the denominator, or your second parameter.

$5 * 6 = 30$

For the second fraction, $\frac{14}{15}$ , you need to multiply both parameters by 2, similar to before, but we now must use a different number, otherwise, the denominators will not be the same.

$14 * 2 = 28$

Now, multiply 15 by 2

$15 * 2 = 30$

The last step is to put these numbers you gathered into fractions. The bigger number always goes on the bottom, referred to as the denominator, while the smaller number, referred to as the numerator, always goes on the top.

$25~and~30 -- > \frac{25}{30}$
