PLEASE HELP ME ASAP I HAVE 2 QUESTIONS

(1)
Eliza and Jamie are making cupcakes for a bake sale at school.Eliza needs 2 1/3 cups of flour for her recipe, and Jamie needs 1 3/4 cups for her recipe. they have 4 cups of flour.Do they have enough flour for both of their recipes? explain.

(2)
last Wednesday it snowed 3 1/4 in. on Sunday it snowed 3 4/5 in. On which day did it snow more? how much more?

Respuesta :

1.) Yes they have enough flour for both of their recipes because if you find the common denominator for both of the flour cups of flour for the recipe which of course the denominator is going to be 12. so the equation would look like this 1 9/12+2 4/12. You add the mixed numbers which it makes 3 and you add the fractions which make it 13/12 you add the 1 to the 3 which makes it have enought flour. So they have 1/12 of it left over. 
2.)  It snowed more yesterday. It snowed 11/20 more inches. hope that helped

Q1: First we want to convert both fractions to common denominators:
2 1/3 ---> 2 4/12
1 3/4 ---> 1 9/12

Add them together 3 13/12 = 4 cups 1/12
They do not have enough flour.

Q2: Again, you want to convert the fractions into fractions with common denominators:
3 1/4 = 3 5/20
3 4/5 = 3 16/20

It snowed more on Sunday
