How do I solve this problemChad buys peanuts in 2 pound bags. He repackages them into bags that hold 5/6 pounds of peanuts. How many 2 pound bags of peanuts should Chad buy so that he can fill the 5/6 pound bags without having any peanuts left over?

Answers

Try dividing 5/6 and 2 (ex: 2 ÷ 5/6) and I think that you should get your answer.

Madame curie made some radium in her lab. she used 2/5 kg of the radium in an experiment and had 1 1/4 kg left. how much radium did she have at first?

Answers

Madame Curie had 1(13)/(20) kg of radium at the beginning.

Further Explanation

Madame Curie used ²/₅ kg for experiment

Radium left = 1¹/₄ kg

Question:

How much radium did she have at first?

The amount of radium that Madame Curie had at first :

= Radium for experiment+ the amount of radium left

\boxed {= (2)/(5) + 1(1)/(4) }\n

we can do the additional if the denominator is the same, if not we need to find a common denominator, in this problem, the common denominator for 5 and 4 is 20, so the equation would be:

we change the mixed fraction into an improper fraction

\boxed {=(2)/(5) + 1(1)/(4) }  \n\boxed {=(2)/(5) + (5)/(4) =( (2 *4)/(5 *4)) + ((5 *5)/(4 *5)) }  \n\boxed {= (8+25)/(20) =(33)/(20) = 1(13)/(20)  }

So, at first, Madame Curie had 11(13)/(20) of radium
