Answer:
See the detailed answers below
Step-by-step explanation:
Given data
Ratio= 1:4:7
combined ratio= 1+4+7= 12
Total amount= $636,000
Apply the part to all method
The first person will take
1/12= x/ 636,000
cross multiply
12x= 636,000*1
x= 636,000/12
x= 53000
The second person will take
4/12= x/ 636,000
cross multiply
12x= 636,000*4
x= 2544000/12
x= 212000
The third person will take
7/12= x/ 636,000
cross multiply
12x= 636,000*7
x= 4452000/12
x= 371000

Answer:
x=35 y=21
Step-by-step explanation:
x:y=5:3 x is in the 5 times table and y is in the 3 times table both of them added are in the 8 times table
8*<u>7</u>=56
7*5=35
7*3=21
21+35=56
