You burned 1/2 * 3/4 = 3/8 of them
So you burned 3/8 * 450 = 168.75
and have 5/8 * 450 = 281.25 left
- if it's allowed to count hats in quarters.
If not, you round up, so 169 and 281

Half of 3/4 is 3/8.
3/8 of 450 is 168.75
So I guess you need to burn 169 hats unless you can burn 3/4 of a hat.

450* 1/2 * 3/4 =168.75
==> You have left:281.25
PS: The number here is not integer so I think there must be sth wrong with your question. I would be Ok if you had 400 hats. :D

That's a really weird problem.
3/4 of 450 = 3*450/4 = 1,350/4 = 337.5
Half of that = 168.75
So (for whatever reason) you have burned 168.75 hats.
How many remain? Subtract from 450
450 - 168.75 = 281.25 hats remain

ok thats funy..who burns hats?..i guess you cant wear all of them that's why you burn 'em right? lol
but seriously..its fairly simple.....
450 hats . three quarters is about 337 whole hats and a half of a hat. half of that are 168 hats and a three quarters of a hat .(the very no. of hats you burned)
About the second question,281 whole hats and a quarter of a hat are still "unburned''
Ps. i didn't use a calculator (earth language: im not a dumb blonde!)

before everything, i could propose working in direction of the 2d and third questions employing the template i'm going to furnish for the 1st question. Then examine your solutions to mine. a million) you have been given $13.35, that's 3/5 of the cost. enable's call the cost of the present x. this means that: (3/5)*x = 13.35 How do you sparkling up this equation for x? undergo in suggestions that, normally, (x/y)*(y/x)=a million. that's by way of fact x/x and y/y are the two equivalent to a million. so as to sparkling up for x we've: (3/5)*(5/3)*x = (5/3)*13.35 a million*x = (5*13.35)/3 x=22.25 this means that the full value of the present is $22.25. 2) the comparable steps from (a million) prepare here. employing the comparable guidance, and employing x to be the load of the equipment, you are able to discover that the equation for this subject is: (5/7)*x=40.5 How do you sparkling up for x? hint: the respond is fifty six.7 lbs. 3) you have x brownies and the canines ate 12 of them. what's the equation? attempt it your self till now observing the respond below. The equation is: (3/10)*x = 12 the respond is: You all started with 40 brownies. the subsequent 2 questions are trouble-free conversions. a million) provided that there are 2 pints in each and every quart, what number quarts is 24 pints? 24 pints / 2 pints consistent with quart = 12 quarts 2) provided that there are 8 pints in each and every gallon, what number gallons is 104 pints? employing the comparable technique you have: 104 pints / 8 pints consistent with gallon = 13 gallons

depends on how you handle the remainder. 450 can't be split into 4ths equally.
