### Instruction:
 Jade anajenga mnara wa lego. Ana vipande 100. Kila ngazi inapaswa kuwa na vipande 7 kwa upana. Ikiwa ana vipande 23 vilivyobaki mwishoni, mnara wake una ngazi ngapi?


### Response:
 Ameitumia lego 77 kwa sababu 100 - 23 = <<100-23=77>>77
Ametengeneza ngazi 11 kwa sababu 77 / 7 = <<77/7=11>>11
