Question 1

How do you change a mixed numbee into a top heavy fraction. 7 1/4

Answer 1

Time the whole number by the bottom and add the top number to find the numerator and the denominator stays the same 7x4+1=29 so answer is 29/4

Question 2

How do you change a top heavy(improper) fraction into a mixed number.e.g 22/7

Answer 2

Divide the top by the bottom to get the whole number and the remainder is the numerator,the denominator stays the same. 22➗7=3 r1 so the answer is 3 1/7

Question 3

What are equivalent fractions and how do you make them.

What is equal to 1/4

Answer 3

Equivalent fractions are the same amount just written differently
You can either times or divide the top and the bottom by the same amount to find equivalent fractions.
2/8 is equal to 1/4

Question 4

How do you write a fraction in its simplest form

Answer 4

Divide the top and the bottom by the same amount until there is no number that goes into the top and the bottom

Question 5

How do you add fractions with the same denominator 1/5+2/5

Answer 5

Add the numerators DO NOT ADD THE DENOMINATORS 3/5

Question 6

How do you add fractions with different denominators 3/4+2/3

Answer 6

Find the LCM of the denominators, use this as the new denominator LCM of 3,4 is 12
For each fraction seperately times the top by whatever you times the bottom by
3/4 times top and bottom times 3 to get 9/12
2/3 times top and bottom times 4 to get 8/12
Now just add the numerators 9+8=17 so the answer is 17/12

Question 7

How do you subtract fractions

Answer 7

Same method as adding except you subtract the numerators

Question 8

How do you divide fractions

Answer 8

Turn the divide sign into a times and flip the last fraction

Question 9

How do you multiply a fraction

Answer 9

Times the numerators, then times the denominators
