Sophie shares her cake with her friends. she gives Lionel a quarter and Helen half of the rest. what fraction remains for her

one and a half quaters

Step-by-step explanation:

4/4 is a whole

The they take one 1/4

then that gives you 3/4

which is then 1.5/4 left for you

3/8

Step-by-step explanation:

Hi! So what really helps me sometimes is to draw a circle and split it. I shaded 1/4 (Lionel's quarter) first. Now, there is 3/4 of the cake left. Helen has half of the rest, which means she has half of 3/4. 1/2 of 3/4 (which is basically 1/2 x 3/4) = 3/8. This means Helen has 3/8 of the cake. I then split my circle into eighths and shaded in 3. This left me with 3/8 of the cake left for Sophie. This means the fraction that remains for her is 3/8.  

I hope this helped :)

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

sorry, i'm new here and i'm just trying to figure this out. try quizlet. rate 5* you!
