Would anyone be so kind as to check my answers BEFORE I go over the problems with my child? For some of you math geniuses, these are probably simple, but for someone who is not good @ math, but trying to learn! it can be quite painful. Thanks for reading!
1. Mrs Jones is between 50 and 80 yrs. If you divide her age by 9, the remainder is 1. If you divide her age by 4, the remainder is 1. How old is Mrs. Jones?
ANSWER = I couldn't get this one, as I thought the answer might be 64 if she was 63 but then 16 x 4 = 64 & there's no remainder. 73 was another choice but then it doesn't work with the dividing by 4 again as there's no remainder.
2. Jon counts 50 cars that pass his house. One-fifth of the cars contain more than one person. Of the cars containing only one person, three-fifths are driven by women. Of the cars containing just one person, how many cars are driven by men? ANSWER = ONE FIFTH?
3. What is the smallest prime number that is a divisor of the following after all the arithmetic is completed (13 x 17) + (19 x 23).
ANSWER = When I added the two I got 658. Would 2 be the smallest prime number then?
4. One natural number is 4 times as great as a second natural number. Thr product of the two numbers is 36. What is the sum of two numbers?
ANSWER - I thought it might be 4 and 9 and thus the sum would be 13?
If you have gotten this far, thanks for reading!
