Step-by-step explanation:
make another column with the heading difference. now, the difference between the children's ages will always be the same. so now you have to make the ratio the same.
NOW:
Child A:Child B:difference
3: 2 : 1(3units-2 units)
10 years later
Child A:Child B:difference
7: 6. : 1(7 units-6 units)
since the difference us the same for both ratios, now we can compare between both sets of ratios.
take for example child A:
the number of units increased in 10 years is 7 units-3 units=4 units
4 units is 10 years
1 unit is
and therefore one child is 5 years old and the other is 7 and a half.
NOTE: IT IS THE SAME IF YOU USED CHILD B.
take for example child B:
the number of units increased in 10 years is 6 units-2 units=4 units
and if you continue to solve, you will find that you arrive at the same answers.
hope this helps!!!!
