Question
1. what is the most $0.41 stamps you can buy for $7.31

2. Find 35% of 63.

3. Ci=onvert 87.5% to a common fraction in lowest terms.

4. write 4.956 x 10^7 in decimal form.

5. A dozen screws weigh 12 0z. Find the weight of 360 such screwa in pounds

Answer
1.)
7.31/.41 = 17.83

ANS : 17, because if you bought 18, you would have to pay more, so 17 is the answer without going over $7.31

---------------------------

2.)
.35 * 63
(63 * 35)/100
22.05

-------------------------

3.)
87.5% = 87.5/100 = 875/1000 = 35/40 = 7/8

------------------------

4.)
4.956 * 10^7 = 49,560,000

---------------------------

5.)
12oz/12 = 1 so each screw ways one ounce, so 360 screws ways 360oz

360/16 = 22.5 lbs

another way to do this is

360/12 = 30
30 * 12 = 360
360/16 = 22.5
