OMG !!!!!!! I HAVE THE SAME QUESTION TO ASK
"Since the ratio is 5:7 you can think in total there was 12 equal blocks of money invested. 5 of those blocks belonged to Jim and 7 of those blocks belonged to Gail. Since they invested $3,600 and then made $6,450 in total there is $10,050. Divide that total into 12 equal blocks of $837.50 and 5 of those blocks belong to Jim. So he will get $4,187.50"
At every 1.0 unit, boiling point decreases 1.8 unit, which means the slope m = -1.8.
2/5 because 10/10 minus 6/10 equals 4/10 which reduces to 2/5
No, It can not be a multiple of any other but itself
