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(1)/(2)` pound rock is 1.571 times heavier than
`10(1)/(2)` pounds rock.

Explanation:

Since we have given that

Quantity of rock =
`16(1)/(2)\ pounds=(33)/(2)\ pounds`

Quantity of another rock =
`10(1)/(2)=(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

`(33)/(2)/ (21)/(2)\\\\=(33)/(2)* (2)/(21)\\\\=(33)/(21)\\\\=1.571`

Hence,
`16(1)/(2)` pound rock is 1.571 times heavier than
`10(1)/(2)` pounds rock.
