For this case we have to know the following conversions:
1 ton = 2204.62 pounds
1 oz = 0.0625 pounds
Now we apply the conversions:
22 tons to pounds:
(22)*(2204.62) = 48501.64 pounds
13 pounds to ounces:
(13)*(1/0.0625) = 208 oz
90,320 ounces to pounds:
(90320)*(0.0625) = 5645
24,000 pounds to tons:
(24000)*(1/2204.62) = 10.88 tons
