For this case we must simplify the following expression:

1 \frac {1} {3}÷ \frac {1} {4}+ \frac {2} {5}÷\frac {1} {4}+ \frac {4} {15}÷\frac {1 }{4}

We convert mixed numbers to improper fractions:

\frac {3 * 1 + 1} {3} ÷ \frac {1} {4} + \frac {2} {5}÷\frac {1} {4} + \frac {4} {15} ÷ \frac {1} {4}=

\frac {4} {3} ÷\frac {1} {4}+ \frac {2} {5}÷ \frac {1} {4}+\frac {4} {15}÷\frac {1} {4} =

We first solve the divisions:

\frac {\frac {4} {3}} {\frac {1} {4}} + \frac {\frac {2} {5}} {\frac {1} {4}} + \frac {\frac {4} {15}} {\frac {1} {4}} =\\\frac {4 * 4} {3 * 1} + \frac {4 * 2} {5 * 1} + \frac {4 * 4} {15 * 1} =\\\frac {16} {3} + \frac {8} {5} + \frac {16} {15} =

We rewrite the fractions:

\frac {16 * 5} {3 * 5} + \frac {8 * 3} {5 * 3} + \frac {16} {15} =\\\frac {80} {15} + \frac {24} {15} + \frac {16} {15} =\\\frac {80 + 24 + 16} {15} =\\\frac {120} {15} =\\\frac {24} {3} =\\8

Answer:

8

Volgvan

The roots of the polynomial are done by using a calculator will be -2.3671, 2.1835 + 1.2527i, and 2.1835 – 1.2527i.

<h3>What are the roots of the polynomial?</h3>

The polynomial is given below.

\rm f(x) = a_0x^n + a_1 x^{n - 1}+ ....+ a_{n-2}x^2 + a_{n-1}x + a_nx^0

The roots of the polynomial are equal to n or less than n.

And if one imaginary root is a + bi, then the other imaginary root will be a – bi.

The roots of the polynomial are done by using a calculator.

x = -2.3671, 2.1835 + 1.2527i, 2.1835 – 1.2527i
