Answer 1

only one question plz help

Answer 2

\(\dfrac{9}{10}-\dfrac{7}{20}\)
first you need common denominators

Answer 3

i think its 11/20, correct?

Answer 4

yup

Answer 5

yay, can you show some work ( a little ) on how to get 11/20?

Answer 6

ok so common denominator of 10 and 20 is 20
you would multiply the denominator 10 by 2 and the numerator 9 by 2 which gives you
\(\dfrac{18}{20}\)

\(\dfrac{18}{20}-\dfrac{7}{20}\)
all you have to do is subtract 18 - 7 and keep the denominator 20
18 - 7 = 11
\(\dfrac{11}{20}\)

Answer 7

\[\frac{ 9 }{ 10 } - \frac{ 7 }{ 20}\]
First we have to bring the base numbers to an equal value
\[\frac{ 9*2 }{ 10*2 } - \frac{ 7*1 }{20*1 }= \frac{ 18 }{ 20 }- \frac{ 7 }{ 20 }\]
when u simplify the equation u will get 11/20 that is the remaining area
