X = advance
y= same day
x+y=70
30x+15y=1650
--------------------------
30x+15y=1650
- x+y=70 (x15) -> 15x+15y=1050
--------------------------
30x+15y=1650
-15x+15y=1050
--------------------------
15x=600
x=600/15
x=40
so now u can insert the price of x AKA the price of the advanced ticket to find our the price of the same day ticket.
x+y=70
so
40+ y=70
y=70-40
y=30
x = advance =40
y= same day =30
Compatible numbers is used to find estimate to a sum. The numbers are chosen because its 'simplicity' when they are multiplied, divided, added or subtracted.
Estimate one:
We can decrease the value 1322 to 1320 and 18 to 15
Then do the sum = 1320÷15 = 88
This estimate is not far from the actual answer 1322÷18 = 73.44..
Estimate two:
We can increase 1322 to 1330 and 18 to 20
Then do the sum 1330÷20=66.50
This estimate is also not far from the actual answer 73.44...
In order to compare two fractions, they must both have the same denominator. In this case, we'll begin by converting 1/4 to twelfths. Multiply the denominator of 1/4 by 3:
4 × 3 = 12
This gives us 1/12. But to avoid changing the overall value of the fraction, we must also multiply the numerator of 1/4 by 3:
1 × 3 = 3
This leaves us with a final value of 3/12. We have now proven that 1/4 is equal to 3/12. This is the answer to your question:
A) 1/4 = 3/12
