Question

whose 57 1/2 % will be 23kg​

Answer 1

Answer:

$57 \frac{1}{2} = \frac{57 \times 2 + 1}{2} = \frac{115}{2} \%$

Now weight be x

$x \times \frac{115}{100} = 23 \\ x = \frac{ \cancel{23} \times\cancel{ 100} {}^{ \: 20} }{\cancel{115} {}^{ \: \: \cancel5} } \\ x = 20 \: kg$

Answer 2

Step-by-step explanation:

x = 57 1/2 % of x = 23

115 / 2× 100 × x = 23

23x/40 = 23

23x / 23 = 40

x = 40
