Answer:

\large\boxed{1\dfrac{16}{19}}

Step-by-step explanation:

5\div2\dfrac{5}{7}\qquad\text{convert the mixed number to improper fraction}\\\\2\dfrac{5}{7}=\dfrac{2\cdot7+5}{7}=\dfrac{19}{7}\\\\=5\div\dfrac{19}{7}=5\cdot\dfrac{7}{19}=\dfrac{(5)(7)}{19}=\dfrac{35}{19}=1\dfrac{16}{19}

5 ÷ 14 + 5/7

Simplify 14 + 5 to 19

5 ÷ 19/7

Use this rule: a ÷ b/c = a * c/b

5 * 7/19

Simplify

35/19

Convert to a mixed fraction

<u>= 1 16/19</u>

Select the correct answer. which expression is equivalent to the given expression? assume the denominator does not equal zero. a
Alexxandr [17]

If the denominator does not equal 0, the equivalent expression of \frac{14x^4y^6}{7x^8y^2} is \frac{2y^{4}}{x^{4}}\frac{x^{10} y^{14}}{729}

<h3>How to determine the equivalent expression?</h3>

The expression is given as:

\frac{14x^4y^6}{7x^8y^2}

Divide 14 by 7

\frac{14x^4y^6}{7x^8y^2} = \frac{2x^4y^6}{x^8y^2}

Apply the law of indices

\frac{14x^4y^6}{7x^8y^2} = \frac{2y^{6-2}}{x^{8-4}}

Evaluate the differences in the exponents

\frac{14x^4y^6}{7x^8y^2} = \frac{2y^{4}}{x^{4}}

Hence, the equivalent expression of \frac{14x^4y^6}{7x^8y^2} is \frac{2y^{4}}{x^{4}}

77julia77 [94]

Answer:

  1194 students last year

Step-by-step explanation:

The problem statement tells us ...

  98% × (students last year) = 1170

Dividing by 98%, we get ...

  1170/0.98 = (students last year) = 1193.88 ≈ 1194

___

<em>Check</em>

1170/1194 = 0.979899... ≈ 0.98 = 98%
