Marcus baked a loaf of banana bread for a party. He cut the loaf into equal size pieces. At the end of the party, there were 6 pieces left. If Marcus told you that 1 4 of the loaf was left, how can you find the number of pieces that were in the whole loaf? Complete the explanation. The denominator in 1 4 is , so I will draw circles to show the equal parts. Since pieces are 1 4 of the loaf, I will draw counters in each circle. By multiplying the number of equal parts by the number of counters in each equal part, I know that there were equal size pieces in the whole loaf.

Mr. M has a recipe for sourdough bread. He uses 8/3 cups of flour to make 2 loaves of sourdough bread. If you were to follow the same recipe, which equation would work for making y loaves of bread with x cups of flour?

Answers

Answer:

2y=8/3x

Step-by-step explanation:

Final answer:

The equation for making y loaves of bread with x cups of flour is x = (4/3) * y.

Explanation:

To find the equation for making y loaves of bread with x cups of flour, we can set up a proportion using the given information. If Mr. M uses 8/3 cups of flour to make 2 loaves of bread, the equation would be:

(8/3 cups)/(2 loaves) = (x cups)/(y loaves)

Cross multiply and solve for x:

8/3 * y = 2x

Simplify the equation to:

4/3 * y = x

So, the equation for making y loaves of bread with x cups of flour is:

x = (4/3) * y
