Question

How many times heavier is a 16 1/2 pound rockthen a 10 1/2 pound rock

Answer 1

A 16 1/2 pound rock is 6 more pounds heavier than a 10 1/2 pound rock.

Answer 2

Answer: $16\dfrac{1}{2}$ pound rock is 1.571 times heavier than $10\dfrac{1}{2}$ pounds rock.

Step-by-step explanation:

Since we have given that

Quantity of rock = $16\dfrac{1}{2}\ pounds=\dfrac{33}{2}\ pounds$

Quantity of another rock = $10\dfrac{1}{2}=\dfrac{21}{2}\ pounds$

We need to find the number of times heavier is 16 1/2 pound rockthen a 10 1/2 pound rock.

so, number of times is given by

$\dfrac{33}{2}\div \dfrac{21}{2}\\\\=\dfrac{33}{2}\times \dfrac{2}{21}\\\\=\dfrac{33}{21}\\\\=1.571$

Hence, $16\dfrac{1}{2}$ pound rock is 1.571 times heavier than $10\dfrac{1}{2}$ pounds rock.
