(Can it be solved by model drawing ?)

A baker had 400 chocolate muffins and 800 blueberry muffins. 1/5 of all the muffins turned bad. The baker sold 160 chocolate muffins and 300 blueberry muffins. If he had 240 fewer chocolate muffins than blueberry muffins(a) What fraction of all the muffins were sold ?
(Give your answer in the simplest form)
(b) how many chocolate muffins turned bad ?

Tks.
a) 460/1200=23/60

b) 1/5 x 1200= 240

240 + 160 + 300 = 700 ( sold + bad)

Total muffin left 1200 - 700= 500

Left
B [1u][240] } 500
C [1u]

Choc muffin left
(500 -240)/2=130

Choc bad --> 400 - 160 - 130= 110

If A had 380 stickers in all, how many stickers does B have?

I didn't copy the question wrong. Can it be solved?
Think should be if they had 380 stickers in all, then yes it can be solved by just making the numerator the same (equal fraction concept)
1/6 A = 2/7 B
2/12 A = 2/7B

A--> 12u, B -->7u

19u--> 380
1u--> 20

B --> 7x20=140

:smile:
You are absolutely correct!
Have checked with the teacher and the question is indeed wrong.

Thanks!

can solve this using Algebra ... prob is how to explain to P5 student.

S + T = 709

S + 74 = T - T/5
S = T - T/5 -74
S = (4T - 370)/5

Replace S with the above equation (4T-370)/5

(4T - 370)/5 + T = 709
9T - 370 = 709 x 5
9T = 3545 + 370
9T/9 = 3915/9
T = 435
S = 709 - T
S = 709 - 435
S = 274
