Sean has a collection of coins. One tenth of the coins are from Europe. Thirty-two hundredth are from Asia. The rest are from Africa. Write a decimal to show the total part of the coins that are from Europe or Asia.

Respuesta :

lets write each part, the total will be x:
(1/10)x = Europe
3200 = Asia
x - (1/10)x - 3200 = Africa

Europe + Asia = (1/10)x + 3200 = x/10 + 3200
= (320x + 1)/3200
that would be expressed as a fraction, and depends on the total of coins, x

Answer: 0.42

Step-by-step explanation:

Let the total number of coins be x.

The part of coins are  from Europe = [tex]\frac{1}{10}[/tex]

Then, the number of coins from Europe = [tex]\frac{1}{10}x=0.10x[/tex]

The part of coins are from Asia =[tex]0.32[/tex]

The number of coins from Asia=[tex]0.32x[/tex]

Now, the number of coins from Europe or Asia =[tex]0.10+0.32x=0.42[/tex]

Hence, the total part of the coins that are from Europe or Asia=0.42
