This past week of math we covered integers and learned about adding, subtracting, dividing and multiplying rational numbers such as fractions. We learned how to convert improper fractions into mixed and vice versa and how to turn decimals into fractions. There are certain rules we learned with adding and subtracting integers, a formula with 2 negative numbers will turn into a positive, adding two positives will have a positive outcome and adding and negative and positive will make a negative. When we divide fractions we learned that we convert mixed fractions into improper fractions and that we flip the reciprocal, multiply the two fractions and reduce to the lowest common denominator. When we add fractions we learnt that if they do not share a common denominator we have to fined their common denominator to properly add or subtract the fractions. Other topics we have learnt are placing decimals and fractions on number lines, we have learned about real numbers, rational numbers, whole numbers, integers, and natural numbers. For my example I will demonstrate how to divide two fractions and the steps that it took me to get my answer. I will also be demonstrating how to convert a mixed fraction into an improper fraction and an improper fraction into a mixed fraction.
Step 1.
flip the reciprocal number
Step 2.
cross reduce your fractions to their lowest form.
Step 3.
multiply your reduced fractions.
Step 4 reduce the new fraction to get your answer.
Step 1
Multiply the the whole number and the denominator.
Step 2
Add the numerator
Step 3
add your mutilped number to the numerator
Step 4
Write the totalled number on top of the same denominator you started with for your answer. (denominator stays the same)
Step 1
figure out how many times the denominator goes into the numerator.
Step 2.
write the the remainder beside the whole number on top of the denominator.
Step 3
Place the whole number on the left hand side of the fraction and keep the denominator the same.
Step 4 to see if you did it write times the denominator by the whole number and add the numerator and see if it is equal to your improper fraction.
