What you're asking is: "How do you answer questions ?" I can't give you
a set of instructions that will work every time. But actually, that's already
been done once. What you need to do is go back to those topics when
they were taught in class, maybe spend some time with the teacher or
a tutor, and give them some attention this time, so that you understand
what those things mean and how to work with them.
Mixed fractions can be converted into improper fractions then changed back to a mixed number.
make each fraction a improper fraction the flip the second fraction and multiply straight across then simplify
You change them into improper or topheavy fractions.
convert into a mixed number.
Convert them to improper fractions with common denominators and proceed normally.
Mixed fractions can be converted into improper fractions then changed back to a mixed number.
You do the numerator divided by the denominator, then simplify the fractions if you can. (this is how you change a improper fraction to a mixed number, you cannot change a proper fraction to a mixed number)
make each fraction a improper fraction the flip the second fraction and multiply straight across then simplify
You change them into improper or topheavy fractions.
convert into a mixed number.
Convert the fractions into equivalent fractions with the same denominator. In actually adding mixed numbers, it is easier to convert the mixed numbers into improper (top heavy) fractions, do the addition, simplify the resulting fraction and convert any resulting improper fraction back into a mixed number.
You change it into an improper fraction, then simplify it, then if you want to, change it back to a mixed number.
Convert them to improper fractions.
Its impossible you can change improper fractions into mixed number, but not 3490000...
Convert them to improper fractions with common denominators and proceed normally.
You can simplify an improper fraction, unless the numbers are prime. Simplify it like how you would regularly, but don't forget that you can always turn it into a mixed number.
Convert them to improper fractions and proceed.
