    oh hey sorry about the wait we can reduce this fraction further \[\frac{110}{100} \] what is 110 divided by 10 and what is 100 divided by 10

    dividing fractions doesn't exist you have to flip the second fraction and you'll end up multiplying instead.

    though for this particular problem, we were just asked to simplify (as in reduce the fractions) , so \[\frac{11}{10} \] is the final answer

    6 and 2 are both even numbers.... they are also divisible by 2 6 divided by 2 is 3 3 x 2 = 6 similarly 2 divided by 2 is 1 1 x 2 = 2

    so the fraction after I reduced would be 3/1 or just 3 3 divided by 1 is just 3 that whole number

    6 is divisible by 2 2 is divisible by 2 so we can divide further until we can't divide anymore 3/1 is the closest I can obtain the simplified fraction. I can't find a common divisible number.

    another example is 6/18 6 is divisible by 6 18 is divisible by 6 6 divided by 6 is 1 18 divided by 6 is 3 so 6/18 in simplified for is 1/3 6 is also divisible by 3 18 is also divisible by 3 but we have to take more steps 6 divided by 3 is 2 18 divided by 3 is 6 2/6 I can simplify further 2 is divisible by 2 6 is divisible by 2 2 divided by 2 is 1 6 divided by 2 is 3 1/3 although I've obtained the same result, using smaller numbers takes too much time.

    I used a bigger number and got a simplified fraction in a step vs using smaller numbers but I'm getting fractions that are still reducible, so I have to reduce further... now I took a bunch of steps. In a timed test, it's a better idea for me to use bigger numbers.

    that's a mixed number... if we want to reduce this fraction or figure out if this fraction can be reduced we need to change it into an improper fraction.

    78 divided by 2 = 39 ------------ ---- 20 divided by 2 10 now we got an odd number on the numerator... we got a problem... 39 is divisible by 3 or 12 10 is divisible by 2 or 5 since none of those divisibility numbers match, we can't reduce further.

    When Meriden made a cake she used a recipe calling for 3/4 cup of sugar. She was planning to make a huge cake for a family get-together, which means that she was going to triple the recipe (three times the ingredients). How much sugar will she need?
