Question

Half of a number from 344 gives 150 . What is the number ?

Answer 1

Answer:

$\frac{1}{194} =0.00515$

Step-by-step explanation:

$Let\:\:the\:\:required\:\:number\:\:be\:\:\:x\\Then,\\344-\frac{1}{x}=150\\\frac{344x-1}{x}=150\\ 344x-1=150x\\344x-150x=1\\194x=1\\x=\frac{1}{194}$

Answer 2

Answer:

388

Step-by-step explanation:    

1/2 of x from 344 = 150

= 344 - $\frac{x\\}{2}$  = 150

= $\frac{344}{1}$ × $\frac{2}{2}$  - $\frac{x}{2}$ = 150

= 688 - x = 150 × 2

= 688 - x = 300

= 688 = 300 + x

= 688 - 300 = x
