Mathematics
1 answer:
Liula [17]3 years ago
4 0

Answer:

\frac{35}{2}

Step-by-step explanation:

To solve this problem we need to write the mixed fraction as a fractional number, as follows:

3 1/3 = 3 + \frac{1}{3} = \frac{9+1}{3} = \frac{10}{3}

5 1/4 = 5 + \frac{1}{4} = \frac{20+1}{4} = \frac{21}{4}

Then, evaluating the expression:

\frac{10}{3}×\frac{21}{4} = \frac{210}{12}

→ \frac{35}{2}

Benny wants to make cookies.To make cookies, he needs 7/3 cups of flour per batch of cookies.If Benny has 7 cups of flour, then
Amanda [17]

Answer:

With 7 cups of flour  3.13 batches of cookies can be made.

Step-by-step explanation:

The amount of flour needed per batch of cookies = 7/3 cups

=  2.33 cup

⇒ 1 batch of cookies = 2.33 cup of flour

or  the ratio of <u>cookie to flour =         1       :      2.33</u>

<u />

Now, the amount of flour Benny has = 7 cups

Let the total batches of cookie made = m

or, ratio of <u>cookie to flour =         m       :      7</u>

So, by the RATIO OF PROPORTIONALITY:

\frac{1}{2.23}  = \frac{m}{7 }

⇒ m = 7 /2.23

or, m   =  3.13

or,  total batches of cookie made = 3.13

Hence, from 7 cups of flour  3.13 batches of cookies can be made.
