Find equivalent fractions with a common denomination 2/3 1/2 5/12

1 answer:

6 0

Hi there!

To find equivalent fractions, we need to multiply both the numerator and the denominator by the same number.

These equivalent fractions are the original fractions multiplied by 2/2:

2/3 = 4/6
1/2 = 2/4
5/12 = 10/24

Hope this helps!

Jon's coin collection consists of quarters, dimes and nickels. If the ratio of quarters to dimes is 5:2, and the ratio of dimes

Margarita [4]

Answer:

The ratio of quarters to nickels is:

15:8

Step-by-step explanation:

To solve the exercise, you must first consider how big is the ratio of each one to the other, when it is mentioned that the ratio of quarters to dimes is 5:2 it means that for every 5 quarters, Jon has 2 dimes, for the more quarters there are with respect to the dimes, we simply divide the larger value by the smaller:

5/2 = 2.5

Thus, we know that there are 2.5 more quarters than dimes. Now the following proportion: the ratio of dimes to nickels is 3:4, which means that for every 3 dimes there are 4 nickels, as the nickels are greater in quantity, we are going to see how many times they are greater in proportion than the dimes making again a division of the major over the minor:

4/3 = 1.33333333333 (we are going to use the fractional number so as not to lose decimals).

As we can see, the nickels are a little more than 1 with respect to the dimes, now we are going to create two formulas with those values:

q = 2.5d
n = 4/3 d

Where:

q = quarters
d = dimes
n = nickels

As you see. We only express the calculated proportions, at first glance you can identify that the number of quarters is greater, but to know how much greater with respect to nickels we are going to divide the two values that accompany "d" in the formulas:

2.5 / (4/3) = 15/8

If we express it in ratio as it is in the exercise, we obtain:

15:8

So, 15:8 is the ratio of quarters to nickels, which means that for every 15 quarters, jon has 8 nickels.

Kimberly is ordering bath towels and washcloths for the inn where she works. The total cost of the order is T=6b+2w, where T is

Setler [38]

Answer:

Step-by-step explanation:

We are given the equation

a) T=6b+2w

T is the total cost

b is the no of bath towels

w is the no of washcloths

so the final equation becomes when T=85

6b+2w=85

b) given budget is $85

6b+2w $\leq$ 85

the maximum no of bath towels will be when wash clothes will be zero

6b + 2(0) $\leq$ 85

6b $\leq$ 85

b $\leq$ 85/6

b $\leq$ 14.16

that means the maximum no of baths towels we can buy is 14

similarly for the maximum no of wash clothes it will be when bath towels will be zero

6(0) + 2w $\leq$ 85

upon solving we get

w $\leq$ 42.5

That means we can buy at most 42 wash clothes.

c) when w = 20

6b + 2(20) $\leq$ 85

6b $\leq$ 45

b $\leq$ 7.5

That means we can buy 7 bath towels when 20 wash clothes are bought to stay in the budget.

Note: omitting the decimal values because a particular objects can't be bought in decimals.

Which of the relations given by the following sets of ordered pairs is a function? {(−5,−4),(−4,−3),(−3,−2),(−4,−5),(−2,−1)} {(0

anzhelika [568]

The relations from the following sets of ordered pairs which is a function is; {(8,1),(−4,1),(3,5),(0,4),(−1,2)}

<h3>Which of the relations given by the following sets of ordered pairs is a function?</h3>

It follows from the definition of a function that a function from an array of X-values to a set Y-values assigns only one Y-value to each X-value.

Hence, it follows from the definition above that the relation; {(8,1),(−4,1),(3,5),(0,4),(−1,2)} is that which is a function.

Dado dos ángulos complementarios, uno mide (2x + 10) y el otro (x + 20),

rusak2 [61]

Answer:

El valor de x es igual a 20 o x = 20.

Step-by-step explanation:

Lo primero que se debe saber es que dos ángulos complementarios suman un ángulo recto o 90º.

Supongamos que el valor de un ángulo $\\ \alpha$ y un ángulo $\\ \beta$ valen:

$\\ \alpha = 2x + 10$ [1]

$\\ \beta = x + 20$ [2]

Como la suma de $\\ \alpha + \beta = 90$ [3]

Entonces

$\\ \alpha + \beta = (2x + 10) + (x + 20) = 90$

Sumamos los factores comunes entre si:

$\\ (2x + x) + (10 + 20) = 90$

Para la primera expresión debemos recordar que se suman sólo los coeficientes. Así:

$\\ (2 + 1)x + (10 + 20) = 90$

$\\ 3x + 30 = 90$

Para despejar la incógnita x, debemos tener en cuenta que una igualdad no se altera si se suma, se resta, se multiplica o divide un mismo valor a cada lado de ella. Por esta razón, para despejar 3x, lo primero que podemos hacer es sumar -30 a cada lado de la expresión (lo que es igual a restar 30 a cada lado de la misma). Así tenemos:

$\\ 3x + 30 - 30 = 90 - 30$
