Answer:

2/5 hours

Step-by-step explanation:

We can write a proportion to solve

1/10 hour x hours

---------------- = -------------------

1/2 package 2 packages

Using cross products

1/10 * 2 = 1/2 x

1/5 = 1/2x

Multiply each side by 2

1/5 * 2 = 1/2x *2

2/5 =x

densk [106]

Answer:

$21/ \frac {1}{8}$

Step-by-step explanation:

Since we're given that a batch requires 3 and one fourths cups of sugar, this is written as

$3/ \frac {1}{4}$

If she wants 6.5 batches then we just cross multiply

1 batch= $3/ \frac {1}{4}$

6.5 batches=x

X= $6.5\times 3/ \frac {1}{4}$

X= $6/ \frac {1}{2}\times 3/ \frac {1}{4}$

X= $\frac {13}{2}\times \frac {13}{4}$

X= $\frac {169}{8}$

X= $21/ \frac {1}{8}$
