Answer:

2/4

0.50

50%

Step-by-step explanation:

If its a diamond or spade then it is it is basically written as 2/4 since there is 4 suits and your trying to pull 2 out of the four. 50% converts to 2/4 and you can turn 50% to decimal by putting a decimal point and a 0 to get 0.50

Answer:

for diamond or spade: 1/2= 0.5 = 50%

Step-by-step explanation:

13/52 = 1/4 to diamond, heart, club or spade

1/4= 0.25

0.25*100% = 25%

If we need to choose diamond or spade,

1/4 for diamond, 1/4 for spade

diamond or spade:   1/4+ 1/4=1/2

1/2 = 0.5 = 50%

john has us and foreign stamps in his album. the ratio of the numer of us stamps to foreign stamps is 5:2. after paul gives him
VLD [36.1K]

Answer:

The number of U.S stamp he has is <u>120</u>.

Step-by-step explanation:

John has us and foreign stamps in his album. the ratio of the number of U.S stamps to foreign stamps is 5:2.

After Paul gives him 12 foreign stamps the ratio becomes 2:1.

Now, to find the number of U.S stamps.

Let the U.S stamps be x.

And the foreign stamps be y.

Now, to solve by using cross multiplication method:

<em>So, the ratio is:</em>

\frac{x}{y} =\frac{5}{2}

By cross multiplying we get:

2x=5y

<em>Dividing both sides by 2 we get:</em>

x=\frac{5y}{2}......(1)

Now, after Paul gives him 12 foreign stamps the ratio becomes:

\frac{x}{12+y} =\frac{2}{1}

<em>By cross multiplying we get:</em>

x=24+2y

Putting the value of x as we get in above equation (1):

\frac{5y}{2} =24+2y

<em>Multiplying both sides by 2 we get:</em>

5y=48+4y

<em>Subtracting both sides by 4y we get:</em>

y=48.

The number of foreign stamps = 48.

Now, to get the number of U.S stamps by putting the value of y in equation (1):

x=\frac{5\times 48}{2}

x=\frac{240}{2}

x=120.

Therefore, the number of U.S stamp he has is 120.
