Change to a mixed number by dividing the upper number of the fratcion with the lower. You put the number you got in front of the fraction, and leave what is left from the division on top of the fraction.
You do not divide into decimal places.
$\frac{14}{5} = 2 \frac{4}{5} \\ 14 \div 5 = 2 \: (4)$
In the example above, we divided 14 by 5, and we got 2, with a remainder of 4.
2 goes in front. 4 on top.

to change a mixed number to a fraction, multiply the number in front with the number under the fraction line and add to the top number
$2 \frac{4}{5} = \frac{14}{5} \\ 2 \times 5 = 10 \\ 10 + 4 = 14 \\ \frac{14}{5}$
Answers for the other numbers:
$\frac{25}{3} = 8 \frac{1}{3} \\ 25 \div 3 = 8 \: (1)$
$\frac{100}{99} = 1 \frac{1}{99} \\ 100 \div 99 = 1 \: (1)$
Fractions are basically another way of writing division.

The Lopez family and the Russell family each used their sprinklers last summer. The water output rate for the Lopez family's spr

grin007 [14]

L = hours used by the Lopez's sprinkler

R = hours used by the Russell's sprinkler

so, we know the Lopez's sprinkler uses 15 Liters per hour, so say after 1 hour it has used 15(1), after 2 hours it has used 15(2), after 3 hours it has used 15(3) liters and after L hours it has used then 15(L) or 15L.

likewise, the Russell's sprinkler, after R hours it has used 40R, since it uses 40 Liters per hour.

we know that both sprinklers combined went on and on for 45 hours, therefore whatever L and R are, L + R = 45.

we also know that the output on those 45 hours was 1050 Liters, therefore, we know that 15L + 40R = 1050.

$\bf \begin{cases}
L+R=45\implies \boxed{L}=45-R\\
15L+40R=1050\\
----------\\
15\left(\boxed{45-R} \right)+40R=1050
\end{cases}
\\\\\\
675-15R+40R=1050\implies 25R=375\implies R=\cfrac{375}{25}\\\\\\ R=15$

how long was the Lopez's on for? well, L = 45 - R.

find the area of this figure. round your answer to the nearest hundredth.use 3.14 to approximate pi.

The area of the geometry is the sum of the area of the triangle and the semicircle will be 49.12 square feet.

<h3>What is Geometry?</h3>

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The geometry is the combination of the semicircle and right triangle.

Then the area of the geometry will be

Area = 1/2 x 6 x 8 + π/8 x 8²

Area = 4 x 6 + 3.14 x 8

Area = 24 + 25.12
