Use fraction rules. And careful use of remainder maths to do it in your head or on a bit of paper.
I'll try and write out how I would do this...
First get rid of the decimal, I hate decimals!.
361/7.6 = 3610/76
Then I tend to attack in stages, helps to think about dishing out marbles....
each 100 gives 1 lot of 76 and a remainder of 24 so we have 36 hundreds to start.
36 remainder (24*36)+10
36 remainder (144+720+10)=874
that's another 8 hundreds so just go round again.
36+8 remainder (8*24)+74
44 r 192+74
44 r 266
46 r 114
47 r 38
47 and 38/76
Did you follow? Each time I just grouped up the remainder and tried to take another batch of 76's out of it, I'm not sure if this is the best way but it works for me and given enough time you can solve anything...
To finish off... simplify fraction - I just go for divide by 2 until I cannot then I get cleverer if I have to.

76 Area = 361 = (side length)^2. This tells us that the length of a side is 19. Perimeter = 4*(side length) = 4*19=76.
just divide that number by 2
76 can be divided by 4... 19 will be the answer that will come after division.

You divide when there is a remainder the same as you divide when there is none. The only difference is that when you divide the last digit in the dividend, you will wither add a decimal point and 0 to the right of the digit and keep dividing, designate the leftover number as a remainder, or you will put the remainder over the divisor to show the remainder as a fraction. For example: 761 divided by 10 is 76 with a remainder of 1. You can write 76 R1, 76 1/10 or 76.1
Aside from 1, the only common factor of 76 and 361 is 19.
76% of 475= 76% * 475= 0.76 * 475= 361
76 Area = 361 = (side length)^2. This tells us that the length of a side is 19. Perimeter = 4*(side length) = 4*19=76.
The GCF is: 19
If the perimeter is 76, then the length of a side is (76/4) = 19 mm.The area is the square of the length of a side = (19)2 = 361 mm2
It is: 6308/76 = 83
just divide that number by 2
1, 2, 4, 19, 38, 76, 361, 722, 1444.
