2 2/7 divided 2 1/2=

Zina [86]

Answer: $\frac{32}{35}$

Step-by-step explanation:

We need to convert the mixed numbers into fractions.

The new numerator will be the sum of the numerator of the fractional part and the product obtained by multiplying the denominator of the fractional part by the whole number part.

The new denominator will the the same denominator of the fractional part.

Then:

$2\ \frac{2}{7}=\frac{2+(2*7)}{7}=\frac{16}{7}$

$2\ \frac{1}{2}=\frac{1+(2*2)}{2}=\frac{5}{2}$

Dividing the fractions, we get:

$\frac{\frac{16}{7}}{\frac{5}{2}}=\frac{16*2}{7*5}=\frac{32}{35}$

Your grades on 4 math tests are 79, 85,

DiKsa [7]

Answer:

The grade on the fifth test that will give you a mean score of at least 85 is 87

Step-by-step explanation:

From the question, the grades on 4 math tests are 79,85,86, and 88.

To determine the grade on the fifth test that will give a mean score of at least 85,

Let the grade on the fifth test be x,

From the formula for mean

Mean = Sum of terms / Number of terms

That is,

85 = (79 + 85 + 86 + 88 + x) / 5

$85 = \frac{79 + 85 + 86 + 88 + x}{5}$

$85 = \frac{338 + x}{5}$

$338 + x = 85 \times 5$

$338 + x = 425\\$

$x = 425 - 338$

$x = 87$

x = 87

Hence, the grade on the fifth test that will give you a mean score of at least 85 is 87.
