A trough contains a certain amount of sand. After Jamie used it to fill a 2.4-kilogram bag, a 650-gram bowl, and a 3-kilogram,125-gram pail, she realized that she had a kilogram of sand left in the trough. How much sand was in the trough at first? Give your answer in grams, using a comma. How many grams of sand in the trough at first?
someone help answer the qustion!!!!!!!!
noice and helped me in my homework and practice:)
1,000g + 2,400g + 650g + 3,125g = 7,175g
7,175g - 1,000g = 6,175g
ssssssssssssssssssssssssssssttttttttttttttttttttttttttttttttttttuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuupppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiidddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd
To find out how much sand was in the trough at first, we need to subtract the weight of all the items Jamie filled from the weight of the sand she had left.
First, let's convert all the weights to grams:
- 2.4 kilograms = 2,400 grams
- 650 grams
- 3 kilograms 125 grams = 3,000 grams + 125 grams = 3,125 grams
Now, add up the weight of the bag, bowl, and pail:
2,400 grams + 650 grams + 3,125 grams = 6,175 grams
Finally, subtract this total weight from the weight of the sand left in the trough:
6,175 grams - 1,000 grams = 5,175 grams
Therefore, there were 5,175 grams of sand in the trough at first.
Remember? 1 kilogram = 1,000 grams (kilo = 1,000)
I'll be glad to check your answer.
