Twenty is what percent of 25?

Mathematics
1 answer:
Alexxandr [17]3 years ago
3 0

Answer:

80%

Step-by-step explanation:

20:25*100 =

(20*100):25 =

2000:25 = 80

Now we have: 20 is what percent of 25 = 80

Question: 20 is what percent of 25?

Percentage solution with steps:

Step 1: We make the assumption that 25 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$.

Step 3: From step 1, it follows that $100\%=25$.

Step 4: In the same vein, $x\%=20$.

Step 5: This gives us a pair of simple equations:

$100\%=25(1)$.

$x\%=20(2)$.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{25}{20}$

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{20}{25}$

$\Rightarrow x=80\%$

Therefore, $20$ is $80\%$ of $25$.

The answer is 48 mph. You take the two numbers and add them. Then divide by two since there are two numbers. Then you should get the overall average.

O<br> Decrease 40 by ratio of 4:5
Reika [66]

A decrease in the ratio 4:5 implies that :

New quantity:Old quantity = 4:5

Let the new quantity be \bf \: x

\bf∴ x : 40 = 4:5

=  > \bf \frac{x}{40}  =  \frac{4}{5}

\bf =  > 40 \times  \frac{x}{40}  = 40 \times  \frac{4}{5}

\bf =  > x = 8 \times 4

\bf =  > x = 32

So, the new quantity is 32
