Hey, there !
If you want to know it as a "improper fraction" , you can
Multiply the denominator from the front number
Whatever the denominator and front number is , you add it to the numerator
So, for this problem we first have the multiply the front number from the denominator
Like: 8 (40)
That gives us the answer of: 320
Now we have to add 320 to 21
Like: 320 + 21
That gives us the answer of:341
We keep our denominator (which is "40" )
Your improper fraction would be:
341 / 40
Good luck on your assignment and enjoy your day!

It took a while to get this one, and I must admit, I'm not the best at explaining anything so I'm simply going to leave the answer above to help those who are stuck.
Answer:
Step-by-step explanation:
Let the length and breadth of the rectangle be a,b units respectively.
Then the area will be ab square units.
Now if the length of the rectangle is reduced by 5 units and breadth is increased by 2 units then new length and breadth will be (a−5) units and (b+2) units.
Then new area will be (a−5)(b+2).
Then according to the problem,
(a−5)(b+2)−ab=−80
or, 2a−5b=−70.......(1).
Now if length of the rectangle is increased by 10 units and breadth is decreased by 5 units then new length and breadth will be (a+10) units and (b−5) units.
Then new area will be (a+10)(b−5).
Then according to the problem,
(a+10)(b−5)−ab=50
or, 10b−5a=100
or, 2b−a=20
or, 4b−2a=40......(2).
Now adding (1) and (2) we get
−b=−30
or, b=30.
Putting the value of b in (1) we get, a=40.
Now a+b=40+30=70.
