Answer:
45
Step-by-step explanation:
1/3 of 90
= 1/3 * 90
= 90/3
= 30
Let the missing number be x.
2/3 of x
= 2/3 * x
= 2x/3
30 = 2x/3
Cross multiply,
2x = 30 * 3
2x = 90
x = 90/2
x = 45
Hence,
the missing number is 45.
60 days / 8 workers = 7.5
60 days - 12 days of work done = 48
48 x 7.5 = 360
360/ 12 workers = 30 days to finish rest of the house.
