<h3><u>Dave is 96 years old.</u></h3><h3><u>Jim is 32 years old.</u></h3><h3><u>Bill is 64 years old.</u></h3>
d = 3j
j = 1/2b
64 = (d + j + b)/3
d = 3(1/2b)
d = 1.5b
64 = (1.5b + 1/2b + b)/3
Combine like terms.
64 = (3b)/3
Multiply both sides by 3.
192 = 3b
Divide both sides by 3.
64 = b
Because we have the value for b we can plug it into the other equations to solve for the other ages.
j = 1/2b
j = 1/2(64)
j = 32
d = 3j
d = 3(32)
d = 96

Keep, change, flip
Example: 3/4 divided by 6/8
Step 1: keep 3/4
Step two: change the division sign to a multiplication sign
Step 3: flip 6/8 and make it 8/6
Step 4: multiply it, then that’s your answer to the division problem
4.5 is the answer for you problem
