Answer:

Sammy solves problems at a rate of 4 problems per minute.

Step-by-step explanation:

When comparing two numbers, you can use fractions, decimals or ratios. Note that decimals can often be confusing.

In this case, we will use a fraction ( \frac{x}{y} )

\frac{68 problems}{17 minutes}

68 can be divided by 17.

\frac{\frac{68}{17}problems }{\frac{17}{17}minutes }

\frac{4problems}{1minute}

Each deli sandwhiches made uses 8/8 pound of roast beef.Marisa started with 5 pounds of roast beef and now has 2 3/4 pounds left
OleMash [197]

Answer:

Marisa has made 6 sandwiches.

Step-by-step explanation:

The pounds of roast beef required to make each sandwiches is \frac{3}{8}, and not \frac{8}{8} as erroneously typed in the question.

Given that each deli sandwiches made, uses \frac{3}{8} pounds of roast beef.

Marisa started with 5 pounds, and had 2\frac{3}{4} pounds left.

Thus,

pounds of roast beef used = 5 - 2\frac{3}{4}

                                             = 5 - \frac{11}{4}

                                             = \frac{20 - 11}{4}

                                             = \frac{9}{4}

                                             = 2\frac{1}{4}

Marisa had used 2\frac{1}{4} pounds of roast beef. So that;

the number of del sandwiches made = 2\frac{1}{4} ÷ \frac{3}{8}

                                                    = \frac{9}{4} ÷ \frac{3}{8}

                                                    = 6

Therefore, the number of sandwiches made by Marisa is 6.
