Aileen can read 1.5 pages for every page her friend can read. aileen's mom was very excited and she say to aileen: ''so, if your friend reads 20 pages, you can read 25 in the same time period! '' is aileen's mom correct?

No because 1.5 and 20 = 30 not 25 so mom is not correct.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
