Let the sons age = x
The dads age would be 3x ( 3 times the sons age)
X + 3x = 48
Simplify:
4x = 48
Divide both sides by 4
X = 12
The sons age is 12
What do you need help with?
<u>All you do for this question is cross multiply and divide
</u> <em></em>is over of = x over 100
360/x = 150%/100
<u>3600/150= 24</u>
x=24<u>
