Pam has 4 yards of fabric she needs 2/3 of fabric for each curtain How many curtains can Pam make with the fabric she has?

6

Step-by-step explanation:

Since Pam has 4 yards of fabric and she needs 2/3 yards of fabric for each curtain, the number of curtains that Pam can make with the fabric she has will be the total yards of fabric that she has divided by the fabric needs for each curtain. This will be:

= 4 ÷ ⅔

= 4 × 3/2

= 6

Therefore, she will make 6 curtains

18a

step-by-step explanation:

simply because it is. it's the highest common factor

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
