Quiz part two (my quiz is being graded so I'm doing the questions out of memory)
1) Q:Joseph has 4/5 as many DVDs as John does if Josephs has 56 how many does john have? A: X=70
4/5*X=56
*5 *5
4*X=56*5
4*X=280
!4 !4
X=280!4
X=70
2)Q:Mary had1 7/10 the amount of plants as sarah had. If Mary has 51 plants how many plants does sarah have? A: Y=30
1 7/10*Y=51
17/10*Y=51
*10 *10
17*Y=51*10
17*Y=510
!17 !17
Y=510/17
(solve 510/17 in some way)
Y=30
