What is 4 3/5 - 2 1/4

Mathematics

Bas_tet [7]3 years ago

The answer would be 2 7/20. I got that because you find the most common multiple of each of the numbers, I just went with 20 because you multiply the two denominators and get 20. Then you take the numerator 3/5= 12/20 1/4= 5/20 so then subtract the two whole numbers (4-2) which would be 2. You take the two new numerators and subtract them so it would be 12-5= 7 you keep the denominator and it would end up as 2 7/20 because you can not reduce it. Hope this helps!!

Ted is making a bread recipe that uses three 1/4 cups of flour and a muffin recipe that uses 2 3/4 cups of flour eggs. How much
wlad13 [49]

Amount of flour used in bread recipe = 3 \frac{1}{4} cups

Amount of flour used in muffin recipe = 2 \frac{3}{4} cups

We have to determine how much more flour is in the recipe.

Since, more amount of flour is used in bread recipe than in muffin recipe.

Total amount of more flour = 3 \frac{1}{4} - 2 \frac{3}{4}

= \frac{13}{4} - \frac{11}{4}

= \frac{2}{4}

= \frac{1}{2}

Therefore, \frac{1}{2} more cup of flour is used in bread recipe than in muffin recipe.

Now, we will determine the total amount of flour used in both recipe.

Total amount of flour used in bread and muffin recipe

= 3 \frac{1}{4} + 2 \frac{3}{4}

= \frac{13}{4} + \frac{11}{4}

=\frac{24}{4}

= 6 cups

Therefore, total 6 cups of flour are used in both the recipes.
