Answer :

anniedavies96
1 pound = 1/14 stone
[multiply by 14]
14 pounds = 1 stone
[multiply by 3]
42 pounds = 3 stone
[divide by 4]
42 / 4 pounds = 3/4 stone
[simplify]
21 /2 = 10.5 pounds = 3/4 stone

If one pound is equal to 1/14 of stone, then one stone is equal to 14 pounds.

A cat has a mass of 3/4 stone. Then you have to find 3/4 from 14 pounds. So

[tex] \dfrac{3}{4}\cdot 14=\dfrac{3\cdot 14}{4} =\dfrac{3\cdot 7}{2}=\dfrac{21}{2}=10.5 [/tex].

Answer: cat has a mass of 10.5 pounds.
