<h3>How to find the rational numbers between -3/4 and -2/3?</h3>
In the form of p/q, which can be any integer and where q is not equal to 0, is expressed as rational numbers. As a result, rational numbers also contain decimals, whole numbers, integers, and fractions of integers (terminating decimals and recurring decimals).
given that -3/4 and -2/3
now take L.C.M between these two rational numbers is 12.
now multiply -3/4 with 3 both numerator and denominator

again multiply -9/12 with 4 both numerator and denominator

now multiply -2/3 with 4 both numerator and denominator

again multiply -8/12 with 4 both numerator and denominator

Hence the -36/48 and -32/48 are rational numbers between -3/4 and -2/3

Option C:  is the surface area of the rectangular prism
 is the surface area of the rectangular prism
Explanation:
The height of the rectangular prism is 5 cm
The width of the rectangular prism is 10 cm
The depth of the rectangular prism is 4 cm
We need to determine the surface area of the rectangular prism.
The surface area of the rectangular prism can be determined using the formula,

Substituting  ,
 ,  and
 and  in the formula, we get,
 in the formula, we get,

Multiplying the terms within the bracket, we have,

Adding all the values within the bracket, we get,

Multiplying, we have,

Thus, the surface area of the rectangular prism is 
Hence, Option C is the correct answer.
