Jon's meal costs $15.00
tip - $3.00
equivalent to - 20% of the cost of the meal.
$3 / 20% = 3 / 0.20 = $15
To check:
3/15 = 0.20 * 100% = 20%
15 * 20% = 3
Question 2 is B because 55 in fraction is 55/100 simplified by 11/20
Answer:
x = 17 y= -38
Step-by-step explanation:
x + y = -21
y = x - 55
It doesn't matter whether x or y is 55 less than the other right now.
<u>substitute for y:</u>
x + x - 55 = -21
<u>solve for x:</u>
2x = 34
x = 17
<u>solve for y:</u>
17 + y = -21
y = -38
Unlike fraction 1/7 is converted to equivalent like fraction 2/14 and the sum of 2/14 + 3/14 = 5/14.
As given in the question,
Given fraction is equal to:
1/7=? + 3/14=?
Here there are two fractions
1/7 and 3/14
LCD( least common denominator) of 7 and 14 is equal to 14.
Now make them like fractions
1/7 is equivalent to
( 1/7) × ( 2/2) = 2/ 14
Now 2/14 and 3/14 are like fractions
Sum of like fractions is:
2/14 + 3/14
= ( 2+ 3) / 14
= 5/ 14
Therefore, the conversion of unlike fraction 1/7 to like fraction is 2/14. And sum of 2/14 + 3/14 = 5/14.
The complete question is:
Convert these unlike fractions to equivalent like fractions and add them. You must use the LCD to get the answer correct. If possible, reduce the final sum. 1/7=? + 3/14=?
