Question

6.
What should be subtracted from
8/15 to get 1/20​

Answer 1

Answer:

First,we need to find a common denominator,which,in this case,is 60.Then you times 8/15 by 4 to get 32/60,then times 1/20 by 3 to get 3/60.So,if you subract them by each other,you would get 29/60.The number can't be simplified anymore,so the answer is

29/60

Hope this helped!

Answer 2

Question:

What should be subtracted from $\frac{8}{15}$to get $\frac{1}{20}$

Answer:

Let the missing number be x

$\frac{8}{15} - x = \frac{1}{20}$

$\frac{8}{15} - \frac{1}{20} = x$

$\frac{8 \times 4}{15 \times 4} - \frac{1 \times 3}{20 \times 3} = x$

$x = \frac{32}{60} - \frac{3}{60}$

$x = \frac{32 - 3}{60}$

$x = \frac{29}{60}$
