Stewart walks 2/3 mile each day. List three multiples of 2/3

Answers

The three multiples of 2/3 are 8/3, 4/3 and 6/3.

Given that Stewart walks 2/3 mile each day.

we need to list three multiples of 2/3

You can multiply 2/3 by several whole numbers to determine its multiples. Three 2/3 multiples are listed below:

(2/3) x 4 = 8/3

(2/3) x 2 = 4/3

(2/3) x 3 = 6/3

Simplifying the fractions, we get:

= 8/3 (which can also be expressed as 2 and 2/3)

= 4/3 (which can also be expressed as 1 1/3)

= 6/3 (which simplifies to 2)

Hence the three multiples of 2/3 are 8/3, 4/3 and 6/3.

1/3 ÷ 2 = ?
in fractions

Answers

1/3 ÷ 2 =

1/3 x 2/1. you do this by doing the reciprocal of 2, and then you do KCF ( keep, change, flip,)

keep 1/3 change ÷ to × and flip 2/1 to 1/2.

1/3 x 1/2 = 1/6.

hopefully this helps you
2 is also the fraction 2/1, so the question is:
(1)/(3) / (2)/(1)
when dividing fractions, you take the second fraction flip the top number (numerator) with the lower number (denominator) and then change the division sign to multiplication:
(1)/(3) * (1)/(2)
(1)/(6) or one sixth
