Los numeros :
Numero mayor = x
Numero menor = 20 - x
x -( 20 - x) = 4
x - 20 + x = 4
2x = 4 +20
x = 24/2
x = 12
El numero mayor es 12
El numero menor es = 20 - 12 = 8
El producto es = 12*8 = 96
Answer: 45%
Step-by-step explanation: To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. If we want to write 9/20 as a percent, we will need to find a fraction equivalent to 9/20 that has a 100 in the denominator. We can do this by setting up a proportion.
= 
Now, we can use cross products to find the missing value.
900 = 20n
÷20 ÷20 ← <em>divide by 20 on both sides</em>
<em> 45 = n</em>
Therefore, 9/20 is equal to 45 over 100 or 45%.

Answer: 0.45
Step-by-step explanation: In order to write 9/20 as a decimal, we need to find a fraction equivalent to 9/20 with a 100 in the denominator. Notice that if we multiply both the numerator of 9/20 by 5, we get the equivalent fraction 45/100 which we can now write as a decimal. Remember that the hundredths place is two places to the right of the decimal point. So, we can write 45/100 as 0.45.
Therefore, 9/20 is equivalent to 0.45.
Answer:
Perimeter on one face =4× side =8
Hence the side of the cube is 2 units.
So the volume of the cube is (side)^3=(2)^3=8 cubic units
