Question

divide 990 into three parts in the ratio 2:4:5​

Answer 1

Step-by-step explanation:

900 × 2/11

=1800/11

= 163.636

900 × 4/11

= 3600/11

= 327.273

900 × 5/11

= 4500/11

= 409.091

Answer 2

ratio = 2:4:5

let the ratio = 2x,4x,5x

according to question

2x+4x+5x=990

11x=990

X=990/11

X=90

now,

numbers are,

2x=180,4x=360,5x=450

180+360+450=990

hence,it can be divided into three parts as 180,360and 480
