How do I solve this math question

[From: ] [author: ] [Date: 12-08-05] [Hit: ]
E.Correct answer is C but what are the steps to get this answer?hope it would be helpful-Use proportion to solve this : First change 2 pounds into ounces since 1pound=16 ounces so 1/16=2/x then cross multiply and x= 32 ounces .Next since 5 ounces is equal 140 grams and 2 pounds is equal 32 grams we can find how many grams there are in two pounds by using proportion 5/140=32/x cross multiply and we get 5x=4480 then we divide 5 by both sides and we get x=896 .-You can make a proportion to solve this. You would say5 is to 140 as 32 is to x.......

solution:

5 ounces = 140 g
=> 1 ounce = 140/5 g = 28 g

now 1 pound = 16 ounces
=> 2 pounds = 16x2 or 32 ounces

now 1 ounce = 28 g
=> 32 ounces = 28x32 or 896 g

hope it would be helpful

Use proportion to solve this : First change 2 pounds into ounces since 1pound=16 ounces so 1/16=2/x then cross multiply and x= 32 ounces .Next since 5 ounces is equal 140 grams and 2 pounds is equal 32 grams we can find how many grams there are in two pounds by using proportion 5/140=32/x cross multiply and we get 5x=4480 then we divide 5 by both sides and we get x=896 .

You can make a proportion to solve this. You would say 5 is to 140 as 32 is to x. It looks like this: 5/140 =32/x....cross multiply, you get 5x= 4480, divide by 5, you get 896.

how many oz are in a lb? I think it is 16 so we will go with that. Thus 2 lb equals 32 oz. Then set up an equation as follows:

5oz/140grams = 32oz/?grams

cross multiply and divide..... (140x32)/5 = 896

5 oz = 140 gm
1 oz = 140/5 gm
2lb = 32oz = 140*32/5 gm = 896 gm
