Hint 2 of 2
Then the 210 g is shared into 7 equal large-sheep portions.
Show solution
Approach: count everything in equal large-sheep portions
- The small sheep eats as much as two large sheep, so pretend it is two large sheep.
- Now there are 5 + 2 = 7 equal large-sheep portions sharing 210 g.
- Each portion is 210 ÷ 7 = 30 g.
- The small sheep gets two portions: 30 + 30 = 60 g, option C.
