Yes, because if you multiply 4/9 by 2, you get 8/18. 
So, yes.

Divide by 2 and find out.

4/9 / 2

Multiply by its reciprocal:

4/9 * 1/2

Multiply the numerators and denominators together:

4/18

4/18 does not equal 8/18, so 4/9 isn't half of 8/18.

Answer:

75 minutes

Step-by-step explanation:

Make an equation

4 pies to 15 minutes = 20 pies to x minutes

4 / 15 = 20 / x

Now cross multiply

4x = 15 × 20

And multiply 15 and 20

4x = 300

Then divide both sides by 4

x = 75

So your answer is 75 minutes

Can some explain how to do this.
KatRina [158]

We can simplify the expression by using exponent properties, and we will see that the correct option is the fourth option.

<h3>How to simplify the expression?</h3>

Remember the exponent property:

\frac{a^n}{a^m} = a^{n - m}

Here we have the expression:

\frac{83.9*10^{12}*2.87*10^{-3}}{3.76*10^2}

We can reorder this to get:

\frac{83.9*10^{12}*2.87*10^{-3}}{3.76*10^2} = \frac{83.9*2.87}{3.76}*\frac{10^{12}*10^{-3}}{10^2}

The right side can be simplified to:

\frac{83.9*2.87}{3.76}*\frac{10^{12}*10^{-3}}{10^2} = 64.04*10{12 - 3 - 2} = 64.04*10^{7}

Now, we can move the decimal point one time to the left and increase the exponent by one, so we get:

6.404*10^8

Then we conclude that the correct option is the last one (where I rounded the expression to only 3 values after the decimal point).
