Answer:

How to find equivalent fractions?

Two fractions are equivalent when they are both equal when written in the lowest terms. The fraction 18/ 20 is equal to 9/ 10 when reduced to the lowest terms. To find equivalent fractions, you just need to multiply the numerator and denominator of that reduced fraction (9/ 10 ) by the same integer number, i.e., multiply by 2, 3, 4, 5, 6 ...

18/ 20 is equivalent to 9/ 10 because 9 x 2 = 18 and 10 x 2 = 20

27/ 30 is equivalent to 9/ 10 because 9 x 3 = 27 and 10 x 3 = 30

36/ 40 is equivalent to 9/ 10 because 9 x 4 = 36 and 10 x 4 = 40

and so on ...

At a glance, equivalent fractions look different, but if you reduce then to the lowest terms you will get the same value showing that they are equivalent. If a given fraction is not reduced to lowest terms, you can find other equivalent fractions by dividing both numerator and denominator by the same number.

What is an equivalent fraction? How to know if two fractions are equivalent?

Finding equivalent fractions can be ease if you use this rule:

Equivalent fractions definition: two fractions a/ b and c/ d are equivalent only if the product (multiplication) of the numerator (a) of the first fraction and the denominator (d) of the other fraction is equal to the product of the denominator (b) of the first fraction and the numerator (c) of the other fraction.

In other words, if you cross-multiply (a/ b and c/ d ) the equality will remain, i.e, a.d = b.c. So, here are some examples:

18 /20 is equivalent to 9 /10 because 18 x 10 = 20 x 9 = 180

27/ 30 is equivalent to 9/ 10 because 27 x 10 = 30 x 9 = 270

36/ 40 is equivalent to 9/ 10 because 36 x 10 = 40 x 9 = 360

Complete the square to transform the quadratic equation into the form (x – p)2 = q.

ryzh [129]

The transformed equation is:

$(x-3)^2 = 23$

Step-by-step explanation:

We have to convert the equation in the form

$(x-p)^2 = q$

Given equation is:

$x^2-6x-8 = 6$

Adding 8 on both sides

$x^2-6x-8+8 = 6+8\\x^2-6x = 14$

In the given equation

a = x

b= ?

So,

$2.x.b = 6x\\b =\frac{6x}{2x}\\b = 3\\$

So 3^2 will be added on both sides

$(x)^2-6x+ (3) = 14+ (3)^2\\(x-3)^2 = 14+9\\(x-3)^2 = 23$

Hence,

The transformed equation is:

$(x-3)^2 = 23$

El sábado he gastado 3/5 del dinero que tenía para el fin de semana, el domingo 3/4 de

Vladimir79 [104]

Answer:

Her original amount of money can be represented by the variable x

Because we are spending one-fourth of her money, and “of” translate to multiply, we can write 1/4(x), or equivalently we can say 0.25x of her money, if you prefer decimal.

When you say 1/2 of it, this refers to the original amount of money, x, unless the problem wants you to figure how much 1/2 of the remaining amount is. So if the problem is directly asking for 1/2 of it, that would’ve half of x, or 0.5x in decimal.

Remaining was 50 pence, so the original amount minus 1/4 of the amount minus 1/2 the amount equals 50 pence or .50 giving us the equation: x-0.25x-0.5x=.50

Combine like terms on the left, and we have 0.25x=0.50.

Divide by 0.25 on both sides.

We have x equals 2.

So she started with $2. To check this, we ask ourselves does having $2, and spending 1/4 of it and spending 1/2 of it, then result to 50 pence?

Yes it does, because 2–1–0.5 does in fact equal 0.50 (50pence)

Su cantidad original de dinero puede ser representada por la variable x Debido a que estamos gastando una cuarta parte de su dinero, y "de" se traduce para multiplicar, podemos escribir 1/4 (x), o equivalentemente podemos decir 0.25x de su dinero , si lo prefiere decimal. Cuando dices la mitad, esto se refiere a la cantidad original de dinero, x, a menos que el problema quiera que calcules la mitad de la cantidad restante. Entonces, si el problema es pedir directamente la mitad, tendría la mitad de x, o 0.5x en decimal. El restante era 50 centavos, por lo que la cantidad original menos 1/4 de la cantidad menos la mitad de la cantidad es igual a 50 peniques o .50, lo que nos da la ecuación: x-0.25x-0.5x = .50 Combina términos semejantes a la izquierda, y tenemos 0.25x = 0.50 Divide por 0.25 en ambos lados, tenemos x igual a 2. ella empezó con 2 dólares. Para comprobar esto, nos preguntamos si tener 2 dólares y gastar 1/4 de ellos y gastar la mitad de ellos, ¿da como resultado 50 centavos? sí eso
