You must have learned "Order of Operations" or PEMDAS by now,
because that's what this whole question is talking about.
Look at the one in the first box:
32 ÷ 4² + 35 - 20 ÷ 5
You know how to do 4², and you know how to do 20÷5, and you know
how to do 4²+35, and you know how to do 35-20 .
But which one should you do first ? ! ?
pEmdas . . . do exponents. 4² = 16
Now you have 32÷16 + 35 - 20÷5
pemDas . . . do division. 32÷16 = 2
and 20÷5 = 4
Now you have 2 + 35 - 4
pemdAs . . . do addition: 2 + 35 = 37
Now you have 37 - 4
pendaS . . . Do subtraction: 37 - 4 = 33 .
That's the whole ugly thing in the first box. It's 33 .
Do the other two boxes the same way. Then you'll have a single number
for each box. Then just line up the three numbers in the order of their size.
This is all just one big PEMDAS exercise. If you do the operations in the
wrong order in one of the boxes, then you'll get the wrong number in that box.

The answer is 18 but let me explain why that is. First of all let's assume (because it's true) that 3/4 is the same as saying 3/4 of one which is the same as saying 3/4 x 1 the answer then to that is 3/4 (go figure) so then using this logic we can say that 3/4 of 24 is the same as 3/4 x 24, which is an easy expression to evaluate if you have a calculator, but what if you don't, then what? Then you have to evaluate, 3/4 x 24 is the same as saying 3 x 24 = 72, then taking 72 and dividing by 4 which will give you 18, the answer. So I hope you can see the connection here, again if we have 3/4 of one we know that's the same as 3/4 x 1 which is equal to 1 x 3 = 3 then divided by 4 which is 3 divided by 4 which is the same as, you guessed, 3/4. Hope that helps, good luck with math in the future.

3 times lindas age (3 time x or 3x) is decreased by 36 (-36), the result (=) is twice lindas age (2 times x or 2x)
now we have
3x-36=2x
subtract 2x
x-36=0
add 36
x=36
age=36
