We should use lb to convert weight to kg

let unknown lb be = X
14 lb = 1 stone
X lb = 9 stone
Cross multiply : X × 1 = 9 × 14
X = 126 / 1 = 126 lb

9 stone = 126 lb
let unknown value of kg be = Y
2.2 lb = 1kg
126 lb = Y kg
Cross multiply : 2.2 × Y = 126 × 1
Y = 126 / 2.2 = 57.3 kg

So 9 stone = 126 lb = 57.3 kg

HOPE IT HELPED !!

What is .336 written as a fraction?
marta [7]
The solution to the problem is as follows:

<span>Write the decimal number as a fraction (over 1)

0.336 = 0.336 / 1
 
Multiplying by 1 to eliminate 3 decimal places
 
we multiply top and bottom by 3 10's
 
Numerator (N) N = 0.336 × 10 × 10 × 10 = 336

Denominator (D) D = 1 × 10 × 10 × 10 = 1000 N / D = 336 / 1000
 
Simplifying our fraction = 336/1000 = 42/125</span>
