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

Step-by-step explanation:

 $(\frac{1}{2}+\frac{3}{4})$÷$\frac{1}{8}$

= $(\frac{1}{2}(\frac{2}{2})+\frac{3}{4})$÷$\frac{1}{8}$

= $(\frac{2}{4}+\frac{3}{4})$÷$\frac{1}{8}$

= $(\frac{5}{4})$÷$\frac{1}{8}$

= $(\frac{5}{4})$x$\frac{8}{1}$

= $\frac{40}{4}$

= 10
