Maya's school held an aluminum collection program in which they collected aluminum and brought it to be recycled. In the first week, Maya collected 4/20 lb of aluminum and her friend Abigail collected 7/8 lb.
a. which girl collected more aluminum?
b. how much aluminum did the two girls collect?
LCM ( Least Common Multiple ) for 8 and 20 = 40
a.
4 / 20 = 4 * 2 / 20 * 2 = 8 / 40
7 / 8 = 7 * 5 / 8 * 5 = 35 /40
Abigail collected more aluminum.
b.
8 / 40 + 35 / 40 =
43 / 40 =
( 40 + 3 ) / 40 =
40 / 40 + 3 / 40 =
1 + 3 / 40 = 1.075lb
Ms.lauren Bradly, why do you care first of all, and second, it's obvios your doing some kind of cheating too if your on this site. So please stop, and think about why your here, it's probably the same reason we're here. Think about it that way.
A)Abigail collected more aluminum.
B) Abigail: 7/8 x 5/5= 35/40
Maya: 4/20 x 2/2= 8/40
35/40 - 8/40= 27/40
This is what I did. You don't need to put in the last part though. I hope this helps!π₯°
