On the first math test, Keiko answered 19 out of 25 questions correctly. On the
m_a_m_a [10]

Answer:

Keiko got a better answer on the test on her second test, and you could compare these two ratios as they are written.

Step-by-step explanation:

First: Convert each of the scores into percentages:

How do you convert ratios to percentages? Well, first we have to convert the ratio to a decimal or a fraction. Let's convert it to a fraction. So, 19 out of 25 will become \frac{19}{25}, and 17 out of 20 will become \frac{17}{20}. To convert a fraction to a percentage:

  • Divide the numerator by the denominator:

19 ÷ 25 = 0.76                                        AND                                    17 ÷ 20 = 0.85

  • Multiply your quotient by 100

0.76 x 100 = 76                                      AND                                 0.85 x 100 = 85

  • Add the percent sign

76%                                                          AND                                                   85%

Now the two quantities are easier to compare. We can obviously see that 85% is bigger [and better] than 76%. So, the ratio that equals 85% - 17 out of 20 - is a better grade.

The second question was: Can you compare these two ratios as they are written? Explain why or why not.

Yes, you can compare these two ratios, just find the [positive] difference between the amount that she scored and the total number of scores that could be gained.

25 - 19 = 6

20 - 17 = 3

Since the equation with 20 and 17 in it has a smaller difference, it is most likely to have a greater value [because that means that Keiko got more right and less wrong, which means a greater mark which is also a greater quantity].

Thanks,

Lashonda, Pablo, and Hong served a total of 143 orders Monday at the school cafeteria. Pablo served 4 times as many orders as Ho
horsena [70]

Answer:

Hong = 25

Pablo = 100

Lashonda = 18

Step-by-step explanation:

Let Hong's order be x , since Pablo served 4 times as many as Hong , then Pablo's order is 4x , also , since Lashonda served 7 fewer than Hong , it means Lashonda's order is x - 7 . combining all

Hong's orders = x

Pablo's order = 4x

Lashonda's order = x - 7

Total order = 143

Then

x + 4x + x - 7 = 143

6x - 7 = 143

6x = 143 + 7

6x = 150

x = 25

Therefore :

Hong served 25 orders

Pablo served 24x 4 orders = 100 orders

Lashonda served 25 - 7 orders = 18 orders
