Answer :

Steps:
1. Do a proportion
8000 pounds/4 tons= 7000 pounds/ x
2. Do 7,000 times 4 which equals 28,000
3. Do 28,000 divided by 8,000
4. Your answer is
3.5 tons

Create a proportion: 8000/4 = 7000/x

8000x = 28000

then divide

8000x/8000 = 28000/8000

that equals x = 3.5 tons

Create a proportion 8000/4 = 7000/x

then simplify to 2000/1 = 7000/x

7000 = 2000x

then divide

7000/2000 = 2000x/2000

3.5 tons = x
