Subtract 8-4 1/2. A. 3 B. 4 C. 4 1/2 D. 3 1/2
Leokris [45]
1.
An expression of the form a \frac{b}{c} is called a "compound fraction"
 
Compound fractions can be written as simple fractions by multiplying c to a, and then adding the product to c as follows:

a \frac{b}{c}= \frac{c.a+b}{c}

for example, 

4\frac{1}{2} can be written as: 

4\frac{1}{2}= \frac{2.4+1}{2}=\frac{9}{2}

2.

when we subtract or add a fraction \frac{m}{n} from an integer k, 

we first write k as a fraction with denominator n. We can do this as follows:

k=k. \frac{n}{n}= \frac{kn}{n}

for example, if we want to subtract \frac{9}{2} from 8, 

we first write 8 as a fraction with denominator 2:

8=8. \frac{2}{2}= \frac{8.2}{2}= \frac{16}{2}

3.

Thus, 

8-4 \frac{1}{2}= \frac{16}{2}- \frac{9}{2}= \frac{16-9}{2}= \frac{7}{2}

4.

The simple fraction 7/2 is not an option, so we write it as a compound fraction as follows:

\frac{7}{2}= \frac{6+1}{2}= \frac{6}{2}+ \frac{1}{2}=3+ \frac{1}{2}=3\frac{1}{2}

(So write 7 as the sum of the largest multiple of 2, smaller than 7 + what is left. In our case these numbers are 6 and 1, then proceed as shown)

Find the value of mn if ab= 9cm, bc= 7.2cm, and LM= 12cm
Alexus [3.1K]

Answer:

9.6 cm

Step-by-step explanation:

Since the shapes are similar, we can write a proportion. Let x be the length of MN.

9/12 = 7.2/x Write a proportion.

9x = 12(7.2) Use cross products.

9x = 86.4 Multiply.

x = 9.6 Divide both sides by 9.

Side MN is 9.6 cm.

Jessie estimates the weight of her cat to be 10 pounds. The actual weight of the cat is 1375 pounds. Find the percent of error.
Sloan [31]

Answer:

The percent error is 99%

Step-by-step explanation

Estimated weight of cat = 10 pounds

Actual weight of cat = 1375 pounds

We need to find the percent of error.

The formula used is: Percent\:Error=\frac{|Estimated\:value-Actual\:Value|}{Actual\:Value}\times 100

Putting values and finding percent of error.

Percent\:Error=\frac{|Estimated\:value-Actual\:Value|}{Actual\:Value}\times 100\\Percent\:Error=\frac{|10-1375|}{1375}\times 100 \\Percent\:Error=\frac{|-1365|}{1375}\times 100 \\Percent\:Error=\frac{1365}{1375}\times 100\\Percent\:Error=0.99\times 100 \\Percet\:Error=99\%

So, the percent error is 99%
