What is the square root of 5 divided by the square root of 15 and simplify and in fraction form

ozzi

Answer:

$\sqrt{\frac{1}{3} }$

$\frac{\sqrt{3} }{3}$

Step-by-step explanation:

The expression $\frac{\sqrt{5} }{\sqrt{15} }$ can be simplified by first writing the fraction under one single radical instead of two.

$\frac{\sqrt{5} }{\sqrt{15} } = \sqrt{\frac{5}{15} }$

5/15 simplifies because both share the same factor 5.

It becomes $\sqrt{\frac{5}{15} } = \sqrt{\frac{1}{3} }$

This can simplify further by breaking apart the radical.

$\sqrt{\frac{1}{3} } = \frac{\sqrt{1} }{\sqrt{3} } = \frac{1}{\sqrt{3} }$

A radical cannot be left in the denominator, so rationalize it by multiplying by √3 to numerator and denominator.

$\frac{1}{\sqrt{3} } *\frac{\sqrt{3} }{\sqrt{3} } =\frac{\sqrt{3} }{3}$

Five pounds is equal to 2.268 kilograms. How many kilograms is 2 pounds?

Tema [17]

Given:

5 pounds = 2.268 kilograms

To find:

The number of kilograms in 2 pounds.

Solution:

We have,

5 pounds = 2.268 kilograms

Divide both sides by 5.

1 pounds = $\dfrac{2.268}{5}$ kilograms

1 pounds = 0.4536 kilograms

Multiply both sides by 2.

2 pounds = 2×0.4536 kilograms

2 pounds = 0.9072 kilograms

Therefore, the correct option is B.
