i know its $1.90 in dollars and cents but the don't know the steps to obtain the answer.

She have left money about $1.90 and it is in a fraction of  

The fraction is a number that represents a part of a whole. The fraction consists of a numerator and a denominator, where the numerator represents the number of equal parts of a whole and the denominator is the total number of parts that make up said whole.  

The three types of fractions are :

To Solve Fraction Questions in Math, we need to:

5.50 + 2.60 = 8.10 ==> This is what that she bought

10.00 - 8.10 = 1.90 ==> This is her change.

It is 1.90 because is so add it to and then subtract it from .

If you have .1 it is equal to 1 tenth, which is equal to . So if you have .9 or .90 it would be equal to or  

$1.90 is in a fraction of

step-by-step explanation:

hello!

to begin with, we're given that on earth, a rock weighs 20 pounds, and while on jupiter, that same rock weighs 42 pounds. now, we're trying to find the weight of a rock that weighs 10.5 pounds on earth, on jupiter.

to solve this, first, set up a proportion, cross-multiply, and solve it algebraically.

setting up the proportion is the hardest and the most confusing part of the problem, but it's simple.

if on earth, the rock weighs 20 lbs, and on jupiter it weighs 42 lbs, our first part of our proportion is 20/42 lbs. the second part has to be equal to each other. this means that 10.5 has to be on the numerator of the fraction, and x, the value we're trying to find, has to be on the denominator. remember that the rock weighs 10.5 lbs on earth, and we're trying to find the weight of it on jupiter (which is x).

20/42 = 10.5/x

next, you would cross-multiply.

20x = 42(10.5)

20x = 441

now, solve it algebraically by using division.

x = 22.05 lbs

this can be rounded to 22.1 lbs.

therefore, the weight of the rock on jupiter is 22.1 lbs, the fourth choice.
