Robin has read 3/4 of a book. mark said he had read 1/2 as much as robin. what fraction of the book has mark read? (show work)

answer: 180

step-by-step explanation:

12-2=10

20-2=18

18x10=180

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

then say something, tell them they won’t respect you if you don’t even have respect for your self sweetheart you need to lay it on them, all of it : )
