Which fraction expresses -30/54 in lowest terms? A. - 10/27
B. - 10/18
C. - 15/27
D. - 5/9


Answer 1
Answer: -30/54 in simplest form:

First, we can start out by finding the greatest common factor (GCF) of the numerator (30) and the denominator (54). To do so, we will list the factors of each number, find the common ones and then the greatest.

Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30
Factors of 54: 1, 2, 3, 6, 9, 18, 27, 54

Look through both sets of factors. Which are the common factors? 1, 2, 3, and 6 are the common factors of 30 and 54. Now, we have the find the greatest common factor. Basically, which number has greater value out of 1, 2, 3, and 6? The GCF is 6.

Second, our last step is to divide the numerator (30) and denominator (54) by our recently found GCF which was 6. This will create a new fraction which is in simplest form.

30 / 6 = 5 \n 54 / 6 = 9

Let's collect our new numerator and denominator and rewrite our brand new fraction in its simplest form.

Which statement is true about the expression 4(9+6)?


This expression can be simplified to
4(15) = 60
The thing true about that is that we can use the distributive property to simplify it. 

4(9+6) = 4*9 + 4*6 = 36 + 24 = 60

A farmer has decided to divide his land area in half in order to plant soy and corn. Calculate the area of the entire area so he knows how much soil is needed. Each bag of soil covers 40 square yards. How many bags should the farmer purchase?
1 bag
2 bags
3 bags
4 bags


The farmer should purchase 2 bags of soil for his farm.

The shape of the farm, according to the picture is a parallelogram. Therefore, the total area can be calculated as follows:

Area = bh


b = base

h = height


base = 6.5 + 2.5 = 9.0 yards

height = 6 yards

Area = 6 × 9 = 54 square yards.

40 square yards requires 1 bag of soil .

54 square yards will require ?

cross multiply

Bags required = 54 / 40 = 1.35 bag

Therefore, the farmer will require 2 bags of soil for his farm.

evelyn read 25 pages of a book on friday morning. she read 1/4 of the remainder on friday afternoon if she still had 90 pages to read after friday afternoon .how many pages were in the book


145 pages.

25 + 1/4 x (X - 25) + 90 = X

100 + X - 25 + 360 = 4X

435 + X = 4X

435 = 3X

X = 145

Ok so we are calling the total number of pages in the book X. Friday morning, they read 25 pages. Friday afternoon, they read 1/4 of what is left. Since they already read 25 pages, we can say that the remainder of the pages is the total, X, minus 25, giving us the amount of pages read on Friday afternoon 1/4 (X - 25). They then say that the rest of the pages in the book after Friday is 90. Therefore what they read of friday plus 90 is the total amount of pages in the book. After this point, it is simple algebraic solving in order to find X. If you plug 145 in for the total amount of pages, you will see that it works.
