(e)4500 3:7:5​

Answer 1

Step-by-step explanation:

a)let the numbers be divided into 5x and 3x

5x+3x=48

8x=48

x=6

number 1=5*6=30

number 2=3*6=18

b)let the numbers be divided into 8x and 7x

8x+7x=90

15x=90

x=6

number 1=8*6=48

number 2=7*6=42

c)let the numbers be divided into 4x and 6x

4x+6x=160

10x=160

x=16

number 1=4*16=64

number 2=6*16=96

d)let the numbers be divided into 9x and 8x

9x+8x=1428

17x=1428

x=84

number 1=9*84=756

number 2=8*84=672

e)let the numbers be divided into 3x,7x and 5x

3x+7x+5x=4500

15x=4500

x=300

number 1=3*300=900

number 2=7*300=2100

number 3=5*300=1500
