Answer 2

Answer: 14.012                    

Step-by-step explanation:

13% of 12.4

= 13/100 * 12.4

=13/1000 * 124

= 13/500 * 62

= 13/250 * 31

= 13 * 31/250

= 403/250

= 1.612

INCREASED AMOUNT: 1.612 + 12.4

                                         14.012

NOTE: REMOVE THE DECIMAL FROM 12.4 AND INCREASE A ZERO TO 100 AND MAKE IT 1000

NOTE: CANCEL THE 13/1000 TO 13/500 AND 13/500 TO 13/250

NOTE: CANCEL THE 124 TO 62 AND 62 TO 31
