(3 + (2/3))(2+(1/2) = 3*2+2*(2/3)+3*(1/2)+((2/3)(1/2)) = 6+(4/3) +(3/2) + (2/6) = 6 + ((8+9+2)/6) = 6 + (19/6) = 6 + 3 + 1/6 = 9 + 1/6 miles = D

Change each mixed number into an equal improper fraction a. 1 7/16, b. 11 5/9, c. 30 5/9, d. 10 10/13, e. 24 3/5, f. 129 1/2

elixir [45]

Answer:

a)

$\dfrac{23}{16}$

b)

$\dfrac{104}{9}$

c)

$\dfrac{275}{9}$

d)

$\dfrac{140}{13}$

e)

$\dfrac{103}{5}$

f)

$\dfrac{259}{2}$

Step-by-step explanation:

<em>" A fraction in which the numerator is greater than the denominator "</em>

We have to change each of the mixed fraction into improper fraction:

We know that the mixed fraction is converted into fraction as:

$a\frac{b}{c}=\dfrac{a\times c+b}{c}$

a)

$1\frac{7}{16}$ could be written as:

$=\dfrac{1\times 16+7}{16}\\\\=\dfrac{16+7}{16}\\\\=\dfrac{23}{16}$

b)

$11\frac{5}{9}$

$=\dfrac{11\times 9+5}{9}\\\\=\dfrac{99+5}{9}\\\\=\dfrac{104}{9}$

c)

$30\frac{5}{9}$

$\dfrac{30\times 9+5}{9}\\\\=\dfrac{270+5}{9}\\\\=\dfrac{275}{9}$

d)

$10\frac{10}{13}$

$\dfrac{10\times 13+10}{13}\\\\=\dfrac{130+10}{13}\\\\=\dfrac{140}{13}$

e)

$24\frac{3}{5}\\\\=\dfrac{24\times 5+3}{5}\\\\=\dfrac{100+3}{5}\\\\\dfrac{103}{5}$

f)

$129\frac{1}{2}\\\\\\=\dfrac{19\times 2+1}{2}\\\\=\dfrac{258+1}{2}\\\\=\dfrac{259}{2}$

uranmaximum [27]

Answer:

1.875\pi square units

Step-by-step explanation:

We know that area of a circle is pi r square.

The sector has a proportional area according to the angle it subtends at the centre.

Here we have a circle of radius 3 inches with central angle 75 degrees.

Total angle of a circle = 360

Area of the given sector = Area of yellow shaded= $\frac{75}{360} *\pi (3^2) \\= 1.875\pi$
