Question

wich number is between 1/3 and 87/100 on a number line

Answer 1

Any number between 0.33 and 0.87

As you know, $\frac{1}{3}$ = 0.33

And,

$\frac{87}{100}$ = 0.87

Therefore, the minimum and the maximum points are 0.33 and 0.87. Therefore, you can choose any number, like 0.44, 0.48, 0.36, 0.56, 0.34, 0.86, 0.78 etc.
