Answer: Benchmark fractions are easy to visualize and identify, and thus, help in estimating the parts. When comparing two fractions with different numerators and denominators, we can either make their denominators common or compare them to a benchmark fraction such as 1/2.

First you will have 1 which is a whole then 1/2 + 1/2 =1 and so on and so forth.

Mixed fractions are like= 2 1/3 4 1/5 They are like whole numbers with fractions as what I mentioned before.

Hope you understand this :)

Answer:

$7x^2+28x$

Step-by-step explanation:

$7x(x+4)\\\\Multiplication\ is\ distributive\ on\ addition\\\\\Rightarrow 7x(x+4)=7(x\times x+x\times 4)\\\\7x(x+4)=7(x^2+4x)\\\\Multiplication\ is\ distributive\ on\ addition\\\\\Rightarrow 7x(x+4)==7\times x^2+7\times 4x\\\\7x(x+4)=7x^2+28x$
