I am not sure what you mean by "tools" but here's a very efficient method (in my opinion) to solving fractions. 

1) Find the LCD (least common denominator)
The LCD of the two fractions given above is 12 

2) Find fractions that are equivalent to the given fractions and as the LCD as the denominator of the equivalent fraction (hmm.. sounds complicated but it really isn't.) 

To get to 12 from 4 you need to multiply 4 by 3. So whatever you do to the denominator you do to the numerator. So 3 x 3 = 9. The equivalent fraction is 9/12. 

To get from 12 from 3 you need to multiply 3 by 4. So whatever you do to the denominator you do to the numerator. So 1 x 3 = 3. The equivalent fraction is 3/12. 

3) Add the numerators
Since you have the denominators of the two fractions now be the same, you are now just to add the numerators of the two (new) equivalent fractions. 

9/12 + 3/12 = 12/12 = 1

(05.01)Which equation can be used to calculate the area of the shaded triangle in the figure below?
Marina86 [1]

Equation of shaded triangle is \frac{1}{2} (14\times8).

Solution:

Length of the rectangle = 14 ft

Breadth of the rectangle = 8 ft

Area of the rectangle = length × breadth

                                    = 14 × 8

In this rectangle the diagonal splits the rectangle into two equal halves.

Area of the shaded triangle = Half of area of rectangle

                                              $=\frac{1}{2} (14\times8)

Area of the shaded triangle = \frac{1}{2} (14\times8)

Hence the equation can be used to calculate the area of the shaded

triangle is \frac{1}{2} (14\times8).

Answer:
115.2 other solutions is 576/5, 115 1/5
Step by step explanation:
To divide by a fraction, multiply by the reciprocal of the fraction
2.4 x (12 x 4)
Then multiply 12 and 4 which is 48
2.4 x 48
Then multiply 2.4 x 48
which is 115.2

suter [353]

Answer: There are 27 minivans out of the vehicles in the parking lot.

Step-by-step explanation:

Since we have given that

Number of vehicles in a parking lot = 45

Part of the vehicles are minivans is given by

\frac{3}{5}

Number of vehicles in the parking lot are minivans is given by

\frac{3}{5}\times 45\\\\=3\times 9\\\\=27

Hence, there are 27 minivans out of the vehicles in the parking lot.

olga2289 [7]

Answer:

0.643

Step-by-step explanation:

Let, s = play a sport

c = participate in a club

P(s) = 0.14

P(s n c) = 0.09

probability that a student participates in

a club given that they also play a sport = P(c | s)

P(c | s) = P(c n s) / P(s)

P(c | s) = 0.09 / 0.14

P(c | s) = 0.64285

= 0.643
