Answer:

  48

Step-by-step explanation:

The total number of "ratio units" is 3+2 = 5, so each stands for 80/5 = 16 items. Then 3 ratio units stand for 3×16 = 48 items.

  3 : 2 = 48 : 32

The first number is 48.

Which is longer, 1/4 of line A or 1/4 of line B? Explain.
rewona [7]

Answer:

1/4 of Line A is SMALLER than 1/4 of line B.

Step-by-step explanation:

Here, two given lines are A and B.

Now,as we can see, From the two lines Line B is LONGER.

⇒ Length of line A < Length of Line B

Now as we know if we MULTIPLY or DIVIDE an inequality by a same positive number on both the sides, then the SIGN DO NOT CHANGE.

Here, divide both sides of the equation by 4, we get:

\implies \frac{\textrm{Length of line A}}{\textrm{4}} <  \frac{\textrm{Length of line B}}{\textrm{4}}\\\implies \frac{1}{4}({\textrm{Length of line A}}) < \frac{1}{4}({\textrm{Length of line B}})

Hence, 1/4 of Line A is SMALLER than 1/4 of line B.

The formula for volume of prism: \frac{1}{2} * <span>length * width * height.
