Answer:
FIRST NUMBER = 20
SECOND NUMBER = 45
Step-by-step explanation:
LET THE RATIO BE X
FIRST NUMBER - 4X
SECOND NUMBER - 9X
A/Q,
=}4X - 5 / 9X - 5 = 3 / 8
CRISS - CROSS ,
=}8 ( 4X - 5 ) = 9X - 5 ( 3 )
=}32X - 40 = 27X - 15
=}32X - 27X = - 15 + 40
=}5X = 25
=}X = 25 / 5
=}X = 5
THEREFORE,
FIRST NUMBER
=} 4X
=} 4 × 5
=} 20
SECOND NUMBER
=} 9X
=} 9 × 5
=} 45
