What number does 55 and 40 both go into? I have 20 minutes left to turn in this assignment and this problem has been a struggle.

Question

55/40 goes into what number to simplify?

Answer 1

We need to find the least common multiple of 55 and 40:

factor 55: 5*11

factor 40: 2*2*2*5

multiply highest power of each factor = 5 * 11 * 2^3 = 440

Answer 2

We first start by listing multiples of one of these numbers.

55: 55, 110, 165, 220, 275, 330, 385, 440, 495

Then we list the multiples of the other number until we see a multiple that matches up.

40: 40, 80, 120, 160, 200, 240, 280, 320, 360, 400, 440

We see that 440 is on the list of multiples for both numbers, so they both go into 440.

Answer 3

the answer is 440. 55 goes into 440 8 times and 40 goes into 440 11 times.
