Question

7/10+2/5-1/10

Answer 1

in order to add/subtract fractions, the denominators must all be the same
so 2/5 = 4/10 right?
now
\[\frac{ 7 }{ 10 } + \frac{ 4 }{ 10 } - \frac{ 1 }{ 10 }\]7+4=11 now that the denominators are the same
11-1=10 add/subtract the numerators
then put it back over the denominator
10/10 = 1

Answer 2

so the correct answer is 1 right

Answer 3

yep :)

Answer 4

Answer 5

for the class photo 1/5 of the students wore jeans 2/10 of the students wore shorts and 4/10 of the students wore a skit what ration of the students wore something else

Answer 6

total minus others
so
\[\frac{ 10 }{ 10 } - \frac{ 2 }{ 10 } - \frac{ 2 }{ 10 } - \frac{ 4 }{ 10 }\]

Answer 7

so is 4/10 the answer

Answer 8

yep :)

Answer 9

but what if you simplify

Answer 10

ah, right
4 and 10 are both divizable by 2 right?
and so 4/2 = 2 10/2 = 5
so 4/10 simplified would be 2/5
