Answer: She brought home 350 centimeters in total
Step-by-step explanation: The question specifies that Jane only had enough money to buy 5/6 of the materials she needed to make her wreath. For her wreath, she would need 180 centimeters of green cloth. However since she can only afford 5/6 of this, what she would end up with is
Green cloth = 180 x 5/6
Green cloth = (180 x5)/6
Green cloth = 900/6
Green cloth = 150 centimeters
Also she would need 240 centimeters of red cloth and since she can only afford 5/6 of the total, she would end up with
Red cloth = 240 x 5/6
Red cloth = (240 x5)/6
Red cloth = 1200/6
Red cloth = 200 centimeters
If she ended up with 150 centimeters of green cloth and 200 centimeters of red cloth, the total length of cloth she would bring home would be
Total = 150 + 200
Total = 350 centimeters
