A group of 2 adults and 4 children spent $38 on tickets to a museum. A group of 3 adults and 3 children spent $40.50 on tickets
Paraphin [41]

Answer:

Divide the 1st equation by 2

a + 2c = 19

Divide the 2nd equation by 3

a + c = 13.5

Subtract the 1st equation and the 2nd equation

c = 5.5

Substituting back into the 2nd equation will give:

a + 5.5 = 13.5

a = 8

Rewrite -4/15 as an equivalent fraction
timofeeve [1]

(\frac{-4}{5} ) in the form of Equivalent Fraction can be written as \frac{-4x}{15x}, where "x" is any integer.

As per the question statement, we are provided with a fraction, (\frac{-4}{5} ).

We are required to rewrite the above mentioned fraction in the form of a general Equivalent Fraction.

To solve this question, we need to know what an equivalent fraction is.

Equivalent fractions are those fractions that have different numerators and denominators but are equal to the same value, when simplified.

For example, (\frac{1}{2}, \frac{2}{4}, \frac{3}{6}, \frac{4}{8}) all equate to \frac{1}{2} when simplified.

Now, for this case, equivalent fractions of (\frac{-4}{5} ) are (\frac{-8}{30}, \frac{-12}{45}, \frac{-16}{60},...), where

\frac{-8}{30}=\frac{(-4)*2}{15*2}\\\frac{-12}{45}=\frac{(-4)*3}{15*3}\\ \frac{-16}{60}=\frac{(-4)*4}{15*4}

i.e., the equivalent fractions of (\frac{-4}{5} ) are in the form of  \frac{-4x}{15x}, where "x" can be any integer, (...-6, -5, -4, -3, -2, -1, 2, 3, 4, 5, 6...)
