Go up 4 Over 3
You go up 4 to go to your slope
And over 3 to get the starting point of that slope
384 pages (0.75) = 288 pages
Add this to the original amount of pages.
384 + 288 = 672 total pages.
Subtracting 3x^4+9x^3+3x^2 from the divided and bringing down 13x.
I think it's suppose to go
6% is .06 divided by 12 which is .005 times the number of months so in this case 9 so 5,000 times .005 times 9 which is 225 so 5,000 plus an interest of 225 adds up to 5,225
You could understand the ration as parts: the total number of parts was 3+7=10.
So girls were 3/10 parts and boys 7/10 parts. The difference was 7-3=4 parts. this difference is equal to 360, so each part is 90 (4*90 =360).
so girls are "3 parts" and each part is 90, then the number of girls is 3*90=270.
