Answer:

  • The first blank is 13, the second blank is 19.

Explanation:

Given

  • Each bag has 10 marbles and each box has 10 bags.

Each box has

  • 10*10 = 100 marbles

Now, to complete the sentences assume the missing value is x.

1) 1 box, x bags and 9 single marbles:

  • 1*100 + 10x + 9 = 239
  • 109 + 10x = 239
  • 10x = 239 - 109
  • 10x = 130
  • x = 13

2) 2 boxes, 2 bags and x single marbles:

  • 2*100 + 2*10 + x = 239
  • 200 + 20 + x = 239
  • 220 + x = 239
  • x = 239 - 220
  • x = 19
