To multiply fractions, all you have to do is multiply the numerator and then the denominator, and then reduce and make into mixed numbers!
7x4=28
8x5=40.
28/4=7
40/4=10

Your answer to this is 7/10!!!!! I hope this helps you!!

Luba_88 [7]

Complete Question

If w'(t) is the rate of growth of a child in pounds per year, what does

$\int\limits^{7}_{4} {w'(t)} \, dt$ represent?

a) The change in the child's weight (in pounds) between the ages of 4 and 7.

b) The change in the child's age (in years) between the ages of 4 and 7.

c) The child's weight at age 7.

d) The child's weight at age 4. The child's initial weight at birth.

Answer:

The correct option is option a

Step-by-step explanation:

From the question we are told that

$w'(t)$ represents the rate of growth of a child in $\frac{pounds}{year}$

So ${w'(t)} \, dt$ will be in $pounds$

Which then mean that this $\int\limits^{7}_{4} {w'(t)} \, dt$ the change in the weight of the child between the ages of $4 \to 7$ years
