there are 45 words on the list
Step-by-step explanation:
let the total words on the list = y
Debra memorised 30 = 2/3 of the total words on the list
2/3 × y = amount of words Debra memorised
2/3 × y = 30
2y/3 = 30
cross multiply:
2y = 3(30)
2y = 90
divide both sides by 2:
2y/2 = 90/2
y = 45
Hence, there are 45 words on the list
