Answer: 48.
Step 1: multiple 90 puzzles x 0.4 to find how many she has already completed = 36.
Step 2: subtract the number completed (36) from the total (90). 90-36 = 54
Step 3: subtract the 6 more she will complete. 54-6 = 48
Answer:
20.
Step-by-step explanation:
Assign variables. The numbers acan be 2x, 3x and 4x. Then, LCM of 2x, 3x and 4x is 12x
12x = 240
(240/12) = x = 20
The HCF of 2x, 3x, and 4x is 20. (Because x is the highest common factor.)
