Find the product and write in lowest term. Give me an integer or simplified fraction.<br> 7/54×27/35
wariber [46]

The product of given expression is \frac{1}{15} \text{ or } 0.0667

<em><u>Solution:</u></em>

Given that we have to find the product and write it in lowest term

Given expression is:

\frac{7}{54} \times \frac{27}{35}

Let us first find common factors of numerator and denominator so, thet simplification becomes easier

54 = 27 \times 3\\\\35 = 7 \times 5

Substituting these in above expression, we get

\rightarrow \frac{7}{27 \times 3} \times \frac{27}{7 \times 5}

Cancel the common factors in numerator and denominator

\rightarrow \frac{1}{15}

In decimal form, we get

\rightarrow \frac{1}{15} = 0.0667

Thus the product of given expression is \frac{1}{15} \text{ or } 0.0667

What's the difference between adding two rational number and get a negative number
nikklg [1K]

Comparing two rational numbers

Use fraction form:

 

Make the denominators the same and compare the numerators. The number with the smaller numerator is smaller. For example, to compare a/b and c/d, we rewrite

 

a/b=a*d/b*d

  = ad/bd and c/d = c*b/d*b=bc/bd

 

Now just compare the numerators : "ad" and "bc"

 

Multiplying and Dividing Rational Numbers 

 

Multiplying and dividing rational numbers in decimal form is the same as multiplying and dividing integers. The decimal place of the product is the same of all decimals of all multiplied numbers. For example, 3.12*2.4.

 

Solution => 3.12*2.4=7.488

 

When multiplying or dividing rational numbers in fractional form, you multiply the numerators (N*N) and then multiply the denominators (D*D).

 

When dividing rational numbers in fractional form, first take the reciprocal of the divisor, and then multiply the numerators and the denominators.

 

Example => 5/9 divided by 2/7 .

 

Solution => 5/9 * 7/2 =  35/18

 

 

Adding Rational numbers

 

Adding and Subtracting rational numbers in decimal form is the same as adding and subtracting integers.

 

Example => -3.54+2.79=-0.75

 

When adding or subtracting rational numbers in fractional form, first make the denominator equal, and then add or subtract the numerators.
