Question

Before conducting some experiments, a scientist mixes 1/2 gram of Substance A with 3/4 grams of Substance B. If the scientist uses 1/8 gram of the mixture for each experience, how many experiments can be conducted?

Answer 1

Answer: 10

Explanation:

`((1)/(2)+(3)/(4))`÷
`(1)/(8)`

=
`((1)/(2)((2)/(2))+(3)/(4))`÷
`(1)/(8)`

=
`((2)/(4)+(3)/(4))`÷
`(1)/(8)`

=
`((5)/(4))`÷
`(1)/(8)`

=
`((5)/(4))`x
`(8)/(1)`

=
`(40)/(4)`

= 10
