1/2 ÷ 3/4=2/3
The number of rows kept empty will be 4 in the meeting room.
The difference between every two successive terms in a sequence is the same this is known as an arithmetic progression (AP).
The arithmetic progression has wider use in mathematics for example sum of natural numbers.
As per the given,
Number of seats in one row = 9
Total number of seats = 126
Maximum number of possible rows =126/9 = 14 rows
Total number of people seated = 90
Number of rows filled = 90/9 = 10 rows
Empty rows = 14 - 10 = 4 rows.
Hence "In the meeting room, four rows will be left unoccupied".

B. If Carl uses the two short pieces,how much more cable would be need?
C. After Carl has used 1 yard of cable,how much cable will he have left?explain your answer
Answer:
A- 5/6 and 1/4
B- 1/12
C- 3/4
Step-by-step explanation:
Given : Carl has three lengths of cable,
Cable 1 - yard long,
Cable 2 - yard long,
Cable 3 - yard long
He needs at least 1 yard of cable.
A. Which two pieces together make a length at least 1 yard and closest to 1 yard?
We can form possible piece together
Taking 5/6 and 1/4
Taking 1/4 and 2/3
Taking 5/6 and 2/3
Length at least 1 yard and closest to 1 yard is the 5/6 yard and the 1/4 yard together.
B. If Carl uses the two short pieces,how much more cable would be need?
The two short pieces 1/4 and 2/3 makes 11/12 of a yard,
So, he would need yards more of cable.
C. After Carl has used 1 yard of cable,how much cable will he have left?
Altogether he has yards of cable.
If he took the 1 cable needed, he would then have 3/4 of a yard leftover.
