Question

How does knowing 1/5 of 10 help you find 3/5 of 10? Draw a picture to explain your thinking.

Answer 1

Answer:

If the problem is,

$\frac{1}{5}\text{ of }10$

By finding it,

Take a 5 box grid in which each box represents 1 unit,

Then take 1 box of this grid,

Repeat this step,

Finally, Add them,

We get,

A grid having 10 boxes with 2 taken boxes,

Thus, $\frac{1}{5}\times 10=2$

When we do these steps for three grids we will get $\frac{3}{5}\times 10$,

That is, by multiplying the result of $\frac{1}{5}\times 10$ by 3 we will obtain $\frac{3}{5}\times 10$

$\frac{3}{5}\times 10=3\times (\frac{1}{5}\times 10)=3\times 2=6$
