Question

Hello! Please help.

Answer 1

1 -

3 cups left.

2-

David biked a total of 158 miles (option C)

Why?

- First exercise:

To solve the problem we need to consider that for each 1/2 cup of cornmeal, we will have 6 corn muffins.

So, calculating we have:

`TotalMuffins=24=4*6\\\\UsedCups=(1)/(2)*4=2Cups`

We can see that, if each 1/2 cups can give us 6 corn muffins, 2 cups can give us 24 corn muffins.

`CupsLeft=5cups-2cups=3cups`

Hence, there are 3 cups left.

- Second exercise:

We can solve the problem by multiplying or adding the fractions according to the number of dots assigned to each one.

So, calculating we have:

`FirstDay=10miles*2=20miles\\SecondDay=10(1)/(2)miles=10.5miles\\ThirdDay=11miles*3=33miles\\FourthDay=11(1)/(2)miles*4=11.5miles*4=46miles\\FifthDay=12miles*3=36miles\\SixthDay=12(1)/(2)miles=12.5miles`

`Total=20miles+10.5miles+33miles+46miles+36miles+12.5miles\\Total=158miles`

Hence, we have that David covered a total 158 miles. (Option C)

Have a nice day!
