Rewrite: 72x3/4<br> please show how you got answer
Alex_Xolod [135]

We have been given the expression

72 \times \frac{3}{4}

We can rewrite the expression as \frac{72\times 3}{4}

In order to simplify the given expression, we can check if we have any common terms in the numerator and denominator.

We can write the term 72 which is in the numerator as 18\times 4

Thus, the expression becomes

\frac{18\times 4\times 3}{4}

We can see that 4 is common in both numerator and denominator. Hence, we can cancel 4. Thus, we are left with

18 \times 3\\&#10;=54

Therefore, we can rewrite the given expression as 54.

maxonik [38]

Answer:

Ben

Step-by-step explanation:

25 goodies = 20 minutes

27 goodies = 24 minutes

Let's use ratio, divide both of them by their minute

25/20 = 20/20

27/24 = 24/24

1.25 goodies = 1 minute

1.12 goodies = 1 minute

1.25 is bigger than 1.12.
