Rosa has 3 3/4 pounds of dough. She uses 3/4 of a pound for one medium loaf of bread. How many medium loaves of bread could be made from Rosa's dough?

It's 5. Divide 3 by 3/4 and that gives you 4 so then add the other 3/4 that she uses so 5, medium loads of bread

3.75 / 0.75 = ?

If you want to do this by the unit factor method, do this.

(0.75 lb/med loaf) x # med loaves = 3.75 lbs. The # med loaves unit cancel so lbs = lbs. Solve for # med loaves. When I was in school I never could remember which number was the numerator and which was the denominator. Doing it by the unit factor method always told me which number was on top and which was on the bottom.

To find out how many medium loaves of bread Rosa can make from her dough, we need to divide the total amount of dough (3 3/4 pounds) by the amount used for a single loaf (3/4 pound).

First, let's convert the mixed number 3 3/4 to an improper fraction:
3 * 4 + 3 = 12 + 3 = 15
So, 3 3/4 is equal to 15/4.

Now, we divide the total amount of dough by the amount used for a single loaf:
(15/4) ÷ (3/4)

When we divide fractions, we invert the divisor and multiply:
(15/4) × (4/3)

Multiplying across, we get:
(15 × 4) / (4 × 3) = 60/12

We can simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 12:
60 ÷ 12 / 12 ÷ 12 = 5/1

Therefore, Rosa can make 5 medium loaves of bread from her dough.
