(1) Subtract 4 times and add 3 to a number, and the result is the same as subtracting 5 times and adding 1 times. Find this number. (using equation)

Let this number be x.

1/4X+3= 1/5X×2

X=20

(2) () divided by 20 = 8 () = () 20 = 1.25.

I don't think 25 is right.

The topic is divided, not divided.

If you divide the last number, divide the first number in reverse order.

Then 20/X= 1.25

The first blank is 16.

X/8= 1.25

The second blank is 10.

20/X= 1.25

The third blank is 16.

P.S. If you typed the wrong question, you missed a word.

If it is divided, the first space is 25. That's right.

Mathematics can't be so sloppy. I pay attention to every word.
