# Dividing whole numbers & fractions: t-shirts

In this math problem, we learn how to calculate the number of baby T-shirts that can be made from 48 yards of fabric. Each T-shirt requires 4/5 yards of fabric. By dividing 48 yards by 4/5 and simplifying, we find out that 60 baby T-shirts can be produced from the given fabric. Created by Sal Khan and Monterey Institute for Technology and Education.

• How could you use the relationship between the numerator and denominator of fractions equivalent to one-half to determine if a fraction is less than one-half?

MATH problem on my daughters homework.
• Hi JoAnn,
The best way to do this type of problem is to get a common denominator and then compare the two values. For example, let's say the question ask, "Is 7/13 less than 1/2?" The common denominator would be 26, so our question becomes, "Is 14/26 less than 13/26?" We can know see that it is not. It is actually greater than 1/2.
• for my sake math is mental abuse to humans
• bro this is 100 human abuse
• 😒I don't Understand😭🤷 But it is cool😒
• If u dont understand Try doing another explanation
• 1/2x +2/3 =1/6
• You have to follow the rule KCC (Keep Change Change.) Example 48 divided by 4/5. You would keep the 48 as it is changing it to 48/1, change the division sign to multiplication, and change the 4/5 to 5/4. Therefore do 48/1 times 5/4. 48 times 5 is 240. 1 times 5 is 5. If we change the 240/5 to a mixed number it would be 48. Hope you understand!
• When u do the repricol process you have to KCF but the thing I don't really understand is the pre-simply part
• You don't have to do the presimplifying. I don't do it, but some people think it makes things easier.
• There are 10 pretzels and 12 kids. What fraction did each kid receive?
• 10/12 = 5/6. Each child got 5/6 of a pretzel.
• bru like when is this going to come useful in my life like
