16 because if you put 16 into a percentage it's 80. 16 divide 20 times 100 equal 80

20 question and gets 80% correct answers.

therefore, 100% - 80% = 20% wrong answers.

20%*20questions = 0.2*20 = 4 questions

A store sells mugs. Each mug costs the same amount. During a sale, the store reduces the price of each mug by $1.75. Wen spends
Sergio039 [100]
I’m assuming the question is what is the price of one mug WITHOUT the sale.

So since the price of 5 mugs is $28.20, we can work out the price of one mug with the sale.

We do this by doing:

$28.20 / 5

Which gives us:

$5.64 per mug during the sale.

To work out the price of a mug without the sale, we simply add on the amount that has been taken off (which we know is $1.75 because the question says so):

$5.64 + $1.75 = $7.39

Therefore we can conclude the price of a mug without a sale is $7.39

And the price of a mug during the sale is $5.64.

I hope this helps!

Answer:

0.6

Step-by-step explanation:

We know that there are 5 counters in total. 3 white and 2 black.

So we know that 3 out of 5 are white and 2 out of 5 are black.

Therefore the chance to get white is 3/5. And for black: 2/5.

We can turn these into decimals, 3/5 = 0.6 (You can make it 6/10 to make it easier.)

And 2/5 = 0.4 (You can make it 4/10 to make it easier.)

Answering the question, you should put your cross/marker on 0.6

What is the correct order of the following numbers from least to greater?<br> 2/3, -0.6, 0.65, 4/5
ExtremeBDS [4]
We can either convert them to decimals or to fractions
if decimals
2/3=0.66666666
4/5=8/10=0.8
so the order is
-0.6, 0.65, 0.66, 0.8 or
-0.6, 0.65, 2/3, 4/5

if conver to fractions then
since -0.6 is negative, it is smallest, no need to convert
0.65=65 hundreths=65/100
2/3=66/99=prety close
4/5=8/10=80/100
order is
-0.6, 65/100, 66/99, 80/100 or
-0.6, 0.65, 2/3, 0.8

Can anyone explain how to solve this?
eduard
I’m not 100 percent sure someone can comment on this and confirm but when it’s written like a fraction it means division. If they gave you the meaning of each variable (the letters) multiply each variable by each coefficient (the number next to the variable). Multiply all of those. Then divide it by the product of 4 and the variable

Hope this helped!
