All of the number already have the same denominator, which is 12 so you can just add them.
(1+5+3)/12=9/12
and subtract then from 1 = 12/12
(12-9)/12=3/12
-9 is equal to -16 ,, -9 = -16
Answer:
83 + 61 = 144
83 - 61 = 22
Step-by-step explanation:
x + y = 144
<u>x - y = 22</u>
2x = 166
x = 83
83 + y = 144
y = 144 - 83
y = 61

Distribution of 500 visitors =100% attendees.
We remove a zero to find 1/10th. By converting 500 } 50/10 = 10 x 50
Step-by-step explanation:
when you add up; 40/10 + 25/10 = 4.0 + 2.5
and show 7.5 is the same as a + b + 1 x 100
and above 7.5 = 175/100 = 1 .75
Or use the counter x = multiply by 50
40/10 + 25/10 = 6.5
6.5-10 = 3.5
x =3.5 x 50
For this last one we can pose new question where 300 visitors was the original total then create new data for new question.
where x = multiply by 30 and create all to tenths etc.
We subtract the shown tenths only to find the total
Then same will apply above with new data.
