Question

divide 1400 into three parts so that the second number is two third of the first and third number four fifth of the second​

Answer 1

Step-by-step explanation:

let first part be x then

second part = 2x/3

third part = 4/5 × 2x/3 = 8x/15

also there sum = 1400

so;

x + 2x/3 + 8x/15 = 1400

15x + 10x + 8x/ 15 = 1400

33x/15 = 1400

33x = 1400 × 15

x = 1400 × 15/33 = 636.363636..........

Answer 2

Step-by-step explanation:

Hello mate

Here is your answer

let the first number be x

then second number will be 2/3x and third number will be 4/5*2/3x=8/15x

A/Q

x+2/3x+8/15x=1400

=> 15x+10x+8x/15=1400

=> 33x=1400*15

=> x =1400*15/33

=>x = 636

then second number = 2/3x=2/3*636=424

and third number = 4/5*424=339.2
