(0.3d-1}{3 1/3}=(\frac{0.84)/7)/(15)

\frac{0.3 d - 1}{3 \frac{1}{3}} = \frac{\frac{0.84}{7}}{15}

d = 3.42222 \dots

Solution steps

\frac{0.3 d - 1}{3 \frac{1}{3}} = \frac{\frac{0.84}{7}}{15}

Convert mixed numbers to improper fractions:

3 \frac{1}{3} = \frac{10}{3}

\frac{0.3 d - 1}{\frac{10}{3}} = \frac{\frac{0.84}{7}}{15}

Apply the fraction rule:

\frac{\frac{b}{c}}{a} = \frac{b}{c \cdot a}

\frac{0.3 d - 1}{\frac{10}{3}} = \frac{0.84}{7 \cdot 15}

Multiply the numbers:

7 \cdot 15 = 105

\frac{0.3 d - 1}{\frac{10}{3}} = \frac{0.84}{105}

Multiply both sides by

\frac{10}{3}

0.3 d - 1 = 0.02666 \dots

Move

1

to the right side

0.3 d = 1.02666 \dots

Divide both sides by

0.3

d = 3.42222 \dots

1 = 4 x

1 = 7 u

(x + a) (x + b) = x^{2} + 5 x + 6

20 x = - 40

- 3 - 0.1 k = 0.4 k
