I believe that the smallest number of students Jimmy can measure is 223, and I know this is right because one of my teachers had us do this probem and she said this was it.
The second one should be correct
He needs 2.5 lbs of sugar and 2.5 lbs of water
since 2.5 if 50% of 5 then thats how much sugar he needs.
10
3 + 12 = 15 So, for every 15 beads, 3 are red. 15 * 3 = 45 So, 9 beads out of 45 are red.
You plug in the numbers. For example, for the first one you plug in 7 to 4.9=0.7m.
You replace the m with 7 then solve. 4.9=0.7(7)
4.9=4.9
which will make the answer infinite solutions since it is a true statement.
