Rancho middle school has an average of 23 3/8 students per teacher.write this mixed number as a decimal.

Answer:

$23\frac{3}{8} = 23.375$

Step-by-step explanation:

Given:

The given mixed number is $23\frac{3}{8}$

We need to write the given mixed number as a decimal.

So, we find the decimal number by separating the parts.

$=23+\frac{3}{8}$

The value of $\frac{3}{8}=0.375$

$=23+0.375$

$=23.375$

Therefore, the decimal number of given mixed number is $=23.375$

On a trip, you had to change your money from dollars to British pounds. You got 560 pounds for 800 dollars. How many pounds will

Lera25 [3.4K]

Answer:

210 pounds

Step-by-step explanation:

First, we are going to find the exchange rate from dollars to pounds.

We know form our problem that 800 dollars are 560 pounds. so:

\frac{560pounds}{800dollars} =0.7

800dollars

560pounds

=0.7 pounds per dollar.

Next, we are going to multiply our exchange rate by the number of dollars we want to change, 300:

300dollars*\frac{0.7pounds}{dollar} =210pounds300dollars∗

dollar

0.7pounds

=210pounds

We will get 210 pounds for 300 dollars
