I'm having problem understanding 2 2/7-1 1/3= can somebody help me with this question.

The first thing we do is change the fractions to equivalent fractions with the same denominator.

2 2/7 = 2 6/21
1 1/3 = 1 7/21

For this problem, we change 2 6/21 to 1 27/21

Now subtract the whole numbers and the numerators.

1 27/21 - 1 7/21 = 20/21

I'm not understanding 3/8 divide by 1/2, can somebody help me with this also. I just don't know what to do.

To divide fractions, we need to use the reciprocal of the divisor and multiply the numerators and the denominators.

(3/8) / (1/2)
(3/8) * (2/1) = 6/8 = 3/4

I don't know how to write 72.4823 in Expanded form. Can somebody show me how

Of course! I'd be happy to help you understand this math problem.

To solve the equation 2 2/7 - 1 1/3, we need to subtract the second mixed fraction from the first mixed fraction.

Step 1: Convert the mixed fractions into improper fractions.

To convert a mixed fraction to an improper fraction, multiply the whole number by the denominator, then add the numerator. The result becomes the numerator, while the denominator remains the same.

For the first mixed fraction, 2 2/7, we multiply 2 by 7 (the denominator) and add 2 (the numerator), which gives us 16. So the first fraction becomes 16/7.

For the second mixed fraction, 1 1/3, we multiply 1 by 3 (denominator) and add 1 (numerator), which gives us 4. So the second fraction becomes 4/3.

Step 2: Find a common denominator for the fractions.

To add or subtract fractions, they need to have the same denominator. In this case, the common denominator is 21 because both 7 and 3 can be multiplied by a whole number to get 21.

Step 3: Convert the fractions to have the common denominator.

To make the first fraction have a denominator of 21, we multiply both the numerator and denominator by 3. So 16/7 becomes 48/21.

To make the second fraction have a denominator of 21, we multiply both the numerator and denominator by 7. So 4/3 becomes 28/21.

Step 4: Perform the subtraction.

Now that both fractions have a common denominator, we can subtract them. Subtracting fraction means subtracting the numerators and keeping the denominator the same.

48/21 - 28/21 = (48 - 28) / 21 = 20/21

Therefore, the solution to the equation 2 2/7 - 1 1/3 is 20/21.
