What is 2.54 as a mixed number?
What is 3.750 as a mixed number?

Answers

$2.54=2+0.54=2+(54)/(100)=2(54:2)/(100:2)=\boxed{2(27)/(50)}\n\n3.750=3.75=3+0.75=3+(75)/(100)=3(75:25)/(100:25)=\boxed{3(3)/(4)}$

2.54 is pronounced two and fifty four hundredths so u would write it exactly as u hear it. 2, and 52 over 100. So, 2.54 is 2 and 54/100. This can be simplified to 2 and 27/50. 3.750 is the same as 3.75 so it is pronounced three and seventy five hundredths. Same as the other example, this is 3 and 75/100. This can be simplified to 3 and 3/4 because both 75 and 100 can be divided by 25.

Attached are pictures of the number lines for each problem. The easiest way to find fractions on a number line is to turn them into a decimal, which is done by dividing the top number by the bottom. For example, 3/5 would be 3 divided by 5.

What number should be added to the expression x^2 + 4x to change it into a perfect square trinomial?

Answers

x^2 + 4x
the number to be added is found by dividing the constant of x by 2
and squared the number
so # to be added = ( 4/2)² = 4
the perfect square trinomial is
x² + 4x + 4 = (x + 2 )² which is a perfect square trinomial
I hope this help you

he number that must be added is four because (x+2)^2=x^2+4x+4
