Answer:

45%

Step-by-step explanation:

To find the percent, we write the information as part/whole:

99/220

Now we convert to a decimal by dividing:

99/220 = 99÷220 = 0.45

Lastly, multiply by 100:

0.45(100) = 45

A decimal number changed to 23.7 after it was rounded. Give a decimal number that is less than 23.7 and another that is greater
mrs_skeptik [129]

Two <em>possible answers</em> are:

23.65 and 23.72.

Explanation:

For the first number, 23.65, we are rounding to the tenths place. 23.65 itself is smaller than 23.7. Looking behind the tenths place, the digit behind it is 5. This means we round the tenths place up; this becomes 23.7.

23.72 is larger than 23.7. We will round it to the tenths place as well. Looking behind the tenths place, we have a 2; this means we "round down." This means leave the 7 as it is and drop the other digits behind it. This gives us 23.7.

A clothing store is having a sale on holiday socks. Each pair of socks costs x dollars. You leave the store with 6 pairs of sock
ss7ja [257]

Answer: $ 14

Step-by-step explanation:

Since, the cost of 1 pair of socks = x

The cost of 6 pair of socks = 6 x

Total amount spend = $ 40

According to the question,

6 x - 14 = 40

6 x = 40 + 14

6 x  = 54

x = 9

Thus, the original price of one pair of socks = $ 9

⇒ The original price of 6 pairs of socks = $ 54

Hence, the total change = original price of socks - the price of socks in the sale = 54 - 40 =  $ 14

Two factors are multiplied and their product it 34.44. One factor is a whole number. What is the least number of decimal places
Tanya [424]
The answer is 2, because if a number is a whole number, for example 2, you must multiply it by a number with 2 decimals, in this case 17.77, to get 34.44 based on this example.


*There are some cases where this doesn't apply, I think, but it does apply for your question.
