What are the equivalent fractions for 1/2 and 1/5 using the least common denominators?

5/10 and 2/10

Step-by-step explanation:

To find equivalent fractions you need to first find the least common denominator. The LCD is always the least common multiple. In this case,  the LCM is 10. Also, it is important to remember that if you multiply one part of a fraction, like a denominator, by a number, you must also multiply the other part.

To get a fraction equal to 1/2 with a denominator of 10, you must multiply the numerator and denominator by 5. This creates the new fraction, 5/10. Then, do this same process with 1/5. To get the denominator of 10 you must multiply the fraction by 2. Thus, 2/10 is the new fraction.

step-by-step explanation:

just keep timing it by 4.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
