Answer:
7 pounds 3 ounces
Step-by-step explanation:
There are 16 ounces in a pound. In order to convert ounces to pounds, we need to see how many 16s fit into 115 (how many full pounds can be made with 115 ounces) and add the remainder as ounces. To do this we can do long division (which gives us 7 remainder 3), or we can divide 115 by 16 (=7.1875) and convert the decimal places to ounces by multiplying 0.1875 pounds (the remainder) by 16 (as there are 16 ounces in pound) which gives us 3 ounces.
So 115 ounces is equal to 7 pounds and 3 ounces.
Hope this helped!
Answer:
84t+64s-360
Step-by-step explanation:
Multiply through by a common factor
120×(1/5t+1/3s) + 120(-3+1/5s+1/2t)
(24t+40s) + (-360+24s+60t)
Group like terms
24t+60t+40s+24s-360
84t+64s-360
