Jeanine is twice as old as her brother Marc. If the sum of their ages is 24. How old is Jeanine?
Take 24 divide by 3 which is 8. 3x8 = 24 if you have 3 groups of 8. 1x8= 8 2x8= 16. 16 is twice as much as 8.
You gotta multiply 24.2=48! You can use the calculator while doing this or by hand it's easy just have to know read the question becarful and then answered
