Question

Oleg made a fraction number line to help him find 4 x2/5

Answer 1

The easiest way to find the number on a number line is to first multiply and then use it as a mixed number. Mixed numbers are generally easier to place on a number line than multiplication or improper fractions. 

4 * 2/5 = 8/5 = 1 and 3/5

Since we have the mixed number of 1 and 3/5 we know we can go just past halfway between 1 and 2 on the number line. 

Answer 2

Answer with explanation:

To find , $4\times \frac{2}{5}$

 we will first mark,  $\frac{2}{5}$ on the number line, and then move,  $\frac{2}{5}$, 4 times in right of number line.

To draw , $\frac{2}{5}$ on the number line, mark 0,1,2,3,....on the number line.Mark four line segments at equal distance between 0 and 1 , which is equivalent to ,$\frac{1}{5},\frac{2}{5},\frac{3}{5},\frac{4}{5},\frac{5}{5}=1,........$.

Now, mark circle on $0, \frac{2}{5},\frac{4}{5},\frac{6}{5},\frac{8}{5}$,

Which gives  $4\times \frac{2}{5}=\frac{8}{5}=1 \frac{3}{5}$.
