So the first thing you want to do when faced with two fractions with different denominators (when subtracting or adding) is to make the denominators the same. So for this equation they would turn out to be p+10/16=15/16 (because 16 is the lowest common denominator, 8 times two) so then you want to subtract 10/16 from 15/16 to isolate the variable (p) which would get: p=5/16 This is the final answer because it cannot be simplified. Hope this helps!
30 divided by 22= 1.36 1.36 minutes for each page, to check 1.36x22= 29.92 1.36x100= 136 minutes. Mary would need about 2 hours and 16 minutes to read a 100 page book.
