Answer:
( I am assuming that these are all fractions)
1. 14 
2. 8
3. 
4. 5 
Step-by-step explanation:
1. First you have to convert 15 into a fraction but it must have the same denominator causing the equation to look like 105/7 - 3/7= 102/7. But you cannot just leave the fraction like that it must be simplified 14 
2. Three-fifths of an hour is 36 minutes. You would next multiply 5 by 60 which would the hours into minutes 5 x 60 = 300. You would then divide 300 by 36 which would give you 8.3333333333, which I just simplified it to 8
3. In order for you to multiply a fraction you would first multiply the top then the bottom. 12 x 6= 72, 15 x 18= 270. The fraction would look like 72/270 which is simplified to
.
4. First I changed the fractions into improper fractions causing the fraction to look like 36/8 x 14/11 (I got these answers by 8 by 4 then adding 4, then for the next fraction I multiplied 11 by 1 then added 3.) 36 x 14= 1224, 11 x 8= 88 the fraction would look like 1,224/88 you would simplify to 5 
Hope this helps
Please tell me if I made any mistakes I enjoy learning from them.

Answer:
A) The side is 14 cm
B) The total distance around the whoole board is 56 cm
Step-by-step explanation:
So we know its a square.
A square is all equal sides
We got the area which is 196
So we know area of a square is L*W or S^2
And since all sides are equal we can square root 196
That would give you 14
So we know each side is 14
Part B is just perimeter, there are 4 equal sides so we can just multiply 14*4 which is 56.
CHECK:
So we want to check the sides are equal
Each side is 14
and area is 196
14*14=196
So its true
