Before conducting some experiments, a scientist mixes 1/2 gram of substance a with 3/4 gram of substance b. if the scientist use 1/8 gram of the mixture for each experiment, how many experiments can be conducted?

Mixing the two ingredients would be adding them together:

1/2 gram + 3/4 gram = 1 1/4 total grams

Divide the total grams by 1/8 to find the number of experiments they can do:

1 1/4 / 1/8 = 5/4 / 1/8 = 5/4 * 8/1 = 40/4 = 10

They can conduct 10 experiments.

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
