Turn both into improper fractions- there easier to work with that way
3 15/16 — 63/16
2 1/4 — 9/4
Then, set it up- you multiply by the reciprocal
63 Divided by 9
__. __
16. 4
Multiply by reciprocal (flipped-second fraction)
63. x. 4
16 9
Cross product- check to see if diagonally the numbers have similar factors- 63 and 9 have 9 in common, 16 and 4 have 4 in common
7. 1
4. 1
1 3/4
Just place dots where the points are saying, the first number is always x aka the horizontal line ( the one that is going down) and the second number is y aka the vertical line ( the one going up)

More algebra pretending to be geometry. These questions should be banished from the planet.
A transversal across parallel lines generates the usual congruent and supplementary angles; here our pair are supplementary, adding to 180 degrees. Geometry done.
(2x + 12.8) + 117.6 = 180
2x = 180 - (12.8 + 117.6) = 49.6
x = 49.6/2 = 24.8
Answer: 24.8
We can get two equations for the two unknowns by using the fact that the perimeters sum to the original length, and that the square's areas are the sum of the squares of the side lengths.
