Answer:

n = 36

Step-by-step explanation:

4 : 5 = n : 45

It can be also written as :-

\frac{4}{5} = \frac{n}{45}

Multiplying both the sides by 45 ,

=> \frac{4}{5} \times 45 = \frac{n}{45} \times 45

=> n = 4 \times 9 = 36

nirvana33 [79]

Answer:

9 magazines

Step-by-step explanation:

To solve this problem you will want to work backwards. Start with the junk mail. There is 18 junk mail and if there are 1/3 as many bills as junk mail then you will need to multiply 18 * 1/3. This equals 6 bills. If there is twice as many bills as letters then you will need to divide bills(6) by 2 which equals 3. If there are 6 more magazines than letters then you need to add 6 to the letters (3). 3 + 6 = 9

erica [24]

Answer:

Step-by-step explanation:

0.25 x 0.044 = 0.011

a. Changing 0.25 to 25 moves the decimal 2 places to the right, and changing 0.044 to 44 moves the decimal 3 places to the right, so once we solve 25 x 44, we have to move the decimal a total of 5 places to the left.

25 x 44 = 1100, then move the decimal 5 places to the left to get 0.01100...but we don't add the zeros at the end.

b. multiplying 1/4 times 0.044 = 0.044/4 = 0.011

Hope this helps.
