Answer:
2/3 hour
Step-by-step explanation:
We can add the fractions, then multiply by the time, or we can multiply each by the time and add the results.
(1/5 +1/3)(1 1/4) = (8/15)(5/4) = (4·2·5)/(3·5·4) = 2/3 . . . hours
alternatively, ...
(1/5)(1 1/4) +(1/3)(1 1/4) = (1/5)(5/4) +(1/3)(5/4)
= 1/4 +5/12 = 3/12 +5/12 = 8/12 = 2/3 . . . hours
It takes Marty 2/3 hours (40 minutes) to shower and eat breakfast.
Answer: the total amount of time
it takes to shower and eat breakfast is 2/3 hour.
Step-by-step explanation:
The total amount of time that it takes Marty to get ready for school is 1 1/4 hours. Converting to improper fraction, it becomes 5/4 hours.
If 1/5 of that time is used to shower, it means that the it takes to shower is 1/5 × 5/4 = 1/4 hour.
If 1/3 of that time is used to eat breakfast, it means that the time it took to eat breakfast is 1/4 × 5/4 = 5/12 hour.
Therefore, the total amount of time
it takes to shower and eat breakfast is
1/4 + 5/12 = 8/12 = 2/3 hour

This means that
This year my salary is: 105% ( up 5% from 100%) ;
Salary = $31500
and last year. 100% ( base year) ; Let the Salary = $x
Now let us solve,
x / 100 = 31500/105
so x = 31500 * 100/105 =
$30 000

Answer:
the sign of the product would be a negative or "-"
Step-by-step explanation:
Final answer:
The sign of the product of -2/9 × 1/7 is negative because one of the numbers being multiplied is negative and the other is positive.
Explanation:
In mathematics, the sign of a product is determined by the sign of the numbers that are being multiplied. When multiplying two numbers, if both numbers are positive or both numbers are negative, the product will be a positive number. If one number is positive and one is negative, the product will be a negative number.
In our case, we are multiplying -2/9 and 1/7. The number -2/9 is negative and the number 1/7 is positive. Since one number is positive and the other one is negative, the sign of the product -2/9×1/7 will be negative. Thus, we enter '-' for negative.
