This is a subtraction problem so subtract 3/4 from 7/8 (7/8 - 3/4). First you have to make them both have the least common denominator. That is 8. So multiply both the numerator and denominator or 3/4 by 2. 3 x 2= 6 and 4 x 2= 8. New fraction is 6/8. Now solve problem again with new fraction. 7/8 - 6/8= 1/8. Your answer is 1/8

Step-by-step explanation:
To estimate an answer to this problem, you must first estimate the numbers as well. 189 would round to 190, and 643 would round to 640. Now you would subtract 190 from 640, giving you 460.
Answer:
$2.40
Step-by-step explanation:
If we know it is $1.08 to make 18 copies. We can do the math to find the rate of 1 copy. This would be by doing 1.08/18=0.06. So, it costs $0.06 to make 1 copy. Now, multiply that by 40 copies 0.06x40=2.40. The cost of 40 copies is $2.40.
