Could someone check over these for me? Thank you soooooooo much!

1.Maria earns $14/hr. Last week she worked 7 hour days for 4 days. What was her gross pay?
$392

2.Arrange the given fractions from smallest to largest. 3/10,1/9,1/12
1/12,3/10,1/9

3.write the following as a common fraction or mixed number. Write your answer in lowest terms.6.38
6 19/50

in #2

3/10 = .3
1/9 = .111...
so 3/1 > 1/9

To check the first question, we need to calculate Maria's gross pay by multiplying her hourly rate by the total number of hours she worked. We are given that Maria earns $14 per hour, and she worked 7 hours a day for 4 days.

To get the total number of hours, we multiply 7 hours by 4 days: 7 x 4 = 28 hours.

Next, we need to calculate the gross pay by multiplying the total number of hours (28) by the hourly rate ($14): 28 x $14 = $392.

Therefore, the answer to the first question is $392.

To check the second question, we need to arrange the given fractions from smallest to largest: 3/10, 1/9, and 1/12.

To compare fractions, we need to find a common denominator. The smallest common multiple of 10, 9, and 12 is 180.

Now, we convert each fraction to have a denominator of 180:

3/10 = 54/180 (multiply numerator and denominator by 18)
1/9 = 20/180 (multiply numerator and denominator by 20)
1/12 = 15/180 (multiply numerator and denominator by 15)

Now that all fractions have the same denominator, we can compare them:

15/180 < 20/180 < 54/180

Thus, the fractions arranged from smallest to largest are 1/12, 1/9, and 3/10.

To check the third question, we need to write the decimal number 6.38 as a common fraction or mixed number in lowest terms.

The whole number part of the decimal, 6, remains the same.

To convert the decimal part, 0.38, into a fraction, we divide it by 1 and multiply the numerator and denominator by 100 to remove the decimal point:

0.38 = 38/100

To simplify the fraction, we can divide the numerator and denominator by their greatest common divisor, which is 2:

38/100 = 19/50

Therefore, the decimal 6.38 can be written as the mixed number 6 19/50 in lowest terms.
