Sisters savings ratio

Sisters Hannah and Jane have saved a total of 560 CZK. A third of Hannah's savings equals a quarter of Jane's savings. How much CZK has Hannah saved, and how much has Jane?

Final Answer:

h =  240
j =  320

Step-by-step explanation:


h+j=560
h/3=j/4

h+j = 560
4h-3j = 0

Pivot: Row 1 ↔ Row 2
4h-3j = 0
h+j = 560

Row 2 - 1/4 · Row 1 → Row 2
4h-3j = 0
1.75j = 560


j = 560/1.75 = 320
h = 0+3j/4 = 0+3 · 320/4 = 240

h = 240
j = 320
