First you need to make both denominators the same number.
The number we can use is 21.
6/7 : to make the denominator 21, you need to multiply the numerator and the denominator by 3.
6 × 3 = 18
7 × 3 = 21
The equivalent is 18/21
1/3 : to make the denominator 21, you need to multiply the numerator and the denominator by 7.
1 × 7 = 7
3 × 7 = 21
The equivalent is 7/21
18/21 + 7/21 = 25/21 = 1 4/21
Answer:
$300
Step-by-step explanation:
25 (hours) x 8 (dollars unit price per hour) = 200 dollars for the hours worked
20 (dollars in tips (every day)) x 5 (days worked) = 100
100 (in tips for the 5 days) + 200 (dollars paid for work) = 300
