How do I do this equation for my son 7.32 - 1.909
2 answers:
1. line up your numbers
2. notice how there is no number above the 9? Imagine a 0 there. You cannot subtract 9 from 0 so you would change the next number over to one less than before (2 to a 1) and carry a ten over to the 0 making it worth ten.
3. subtract 10 from 9 (getting 1)
4. subtract 1 from 0
5. you cannot take 3 away from 9 so you must once again carry a ten. Change the 7 to a 6 and change the 3 to a 13, then subtract 13 from 9
6. subtract 6 from 1
7. you should be left with 5,411. you are going to want to carry down the decimal to make it 5.411
8. you've successfully subtracted decimals
Hope this is helpful! Also this is in a step bye step form :)

Answer:
6.95 feet
Step-by-step explanation:
The shape of the cot is rectangular. A diagonal of the rectangle divides the rectangle into two Congruent Right Angled triangles. The length and width of the rectangle become the legs of the right triangle and the diagonal is the hypotenuse of the right triangle.
In order to find the length of the hypotenuse which is the diagonal in this case we can use the Pythagoras Theorem. According to the theorem, square of hypotenuse is equal to the sum of square of its legs. So for the given case, the formula will be:
Thus, rounded of to nearest hundredth foot, the diagonal distance from corner to corner is 6.95 feet
