9+3=12
30+20=50
300+100=400

Answer:
2/10 = 1/5.
Step-by-step explanation:
There are 2 reds in 10 chALKS.
Vertex is (-2,-3) and it's a minimum.
There are many ways to work this out. One way could be:
Add up:
1/4 + 1/4 + 1/4 = 3/4
Find 3/4 of 8 so;
8 / 4 = 2
2 x 3 = 6
Find what's remaining:
8 - 6 = 2
So Mr.Greg has sandwiches left.
Hope it helped :)
